 The development of networking and communication technologies in recent years brings together individuals with mutual interests using electronic mediation to overcome the same-place same-time limitation inherent in face to face settings. This has completely set a revolution in the way information is acquired, stored and disseminated. A significant transformation of the traditional face-to-face communities to online communities has empowered users of the internet to reach out to their counterpart in a manner that is unimaginable.
-A critical review of online communities will be considered, with the aim to propose a sequence of success attributed to the migration from offline to online communities. Fichter (2005) recognizes considerable number of users in online communities as information consumers, ranging from reading world news to reviewing weather forecast. But acknowledge that many assumed the role of information providers with contribution to important topics such as wikis, blogs, more recently podcasts and videos.

 The task management feature of email as reported by (Bellotti, et al. 2006) reminds the online community members about current task and it relevant maintenance status, by exploring the inbox to ascertain the associated criteria attached to task in question. In another development (Whittaker, et al. 2006) reveals that email serves as very important repository of information, by way of classifying and organizing information into folders to make it accessible in future. Kumar, et al. (2006), states that the advent of large social online communities has empowered people to be interacting in an online setting. This development has contributed to the success and failure of many companies and organizations in the internet space. Because it is evident in the way [[http://www.yahoomail.com|yahoo mail homepage]] engines are managing users of the online communities. Sending and receiving mails via their accounts, freely created and managed.[[Ibrahim.AlhajiBello@mail.bcu.ac.uk|contact bello]]
 ==== 3.2	Discussion forum====
+Raghavan, et al. (2010) describe online discussion forums as web-based communities that allow users to share ideas, post problems, comment on posts by other users and obtain feedback. This makes the large fraction of discussions to be problem solving threads where many members of the forum collaborate to solve an issue faced by a member in hardware or software related. For instance [[http://www.techrepublic.com|techrepublic ]] and [[http://www.vbdotnetforum.com|.netForum ]] are discussion forums that capture participants from software programming and hardware engineering field.
 Balaji and Chakrabarti (2010) state that, discussion forum otherwise known as newsgroup, bulletin board or conference is regarded as the most popular online stage in electronic communication. Because the conversational tune is asynchronous, meaning that is not necessary for people to be present in the same virtual communities at the same time before participation. As such, messages are threaded with the first message starting the thread followed by responses directly beneath it as stated by Lampe, et al. (2010).

 Fiore, et al. (2002) reported that Usenet newsgroups regularly receive noisy and voluminous messages that are mostly of limited value. Despite the merit of collaboration through computer networks, poor quality messages and flood newsgroups content have prove too difficult to be worthwhile. In an earlier research work, (Sack, 2000) highlighted that news browsers would be design to reduce the noise and increasing volume of articles traffic in online communities. So that users will be allowed to sort and search for dates of author’s contribution to messages and threading process in the community of users about a specific topic.
+A flame war is a tendency for a user to go off-topic and attack personality rather than their opinion. Likely candidates for flame wars are usually religion and socio-political topics, or topics that discuss pre-existing rivalries outside the forum.

- The research discusses the unique challenges of balancing security and privacy with usability and sociability. Because it has been observed that illegal disclosure and improper application of member’s private information can result to serious consequences to the online community structure and integrity. The participation of members in the online communities actively, is proportional to the benefits accrued for the individual member and the community as a whole. These contributions will sustain the communities and increase it chances of achieving success.
+ Popular interest in online communities has grown rapidly in recent years, with the recognition that participation is unevenly distributed and that a core subset of actors plays a key role in sustaining the group (Jones, et al. 2004).This development had posed a unique challenges of balancing security and privacy with usability and sociability. The illegal disclosure and improper application of member’s private information can result to serious consequences to the online community structure and integrity.
-However, the study realizes the distinction between accuracy and complexity in describing social relationships and user interaction. Such that inaccurate and ambiguous descriptions will introduce security vulnerabilities, while processing complex descriptions may result to computational costs that make the design and implementation of online communities infeasible in practice.
+The participation of members in the online communities actively, is proportional to the benefits accrued for the individual member and the community as a whole. These contributions will sustain the communities and increase it chances of achieving success. Hence, the research recognizes the significance of the modern technology effort in bridging the gap inherent with the traditional face-to-face setting to virtual communities affordably and comfortably.
-===== 8. Conclusion =====
+The technologies that support the online communities are categories into synchronous and asynchronous mode of response. It was observed that the application of email, discussion forum or instant messaging to pass information across the online communities all depend on the sensitivity and the urgency of delivery attached to the information.
+===== 8. Future directions of online communities =====
+Future research may benefit from ceasing to conflate similarities among online communities and more carefully evaluating the specific context of each online community in fundamental classification. Indeed, even though the online communities share the same topic (technology) and technology platforms, they still demonstrate measurable community-specific differences (Katz and Rice, 2002). This is evident that a future work is needed to ascertain how these findings generalize to a more diverse set of online communities in terms of topics, size, and stage in online community life cycle.
+===== 9. Conclusion =====
-This article discussed the security and privacy implications associated with online communities and pointed out a few research directions for mitigating the design conflicts between the various design goals of OSNs. However, the collaboration of social scientists, network security communities and other relevant field of behavioral sciences will facilitate a secure mechanisms and policies that will enhance the present situation.
+The research of online communities is essentially multi-disciplinary due to the need of good software usability from computer scientists and cordial interaction from social scientists. The aggregation of usability and sociability will produce thriving online communities.
+The security and privacy implications of online communities is an area that  require constant research and development, as fraudsters and intruders  gain access and perpetrate fraud.  However, the collaboration of social scientists, network security communities and other relevant field of behavioral sciences had facilitate a secure mechanisms and policies that will enhance the present situation.
+The classifications of online communities were presented based on pioneer researchers’ opinion. These dimensions were selected from earlier theories of online communities, such that purpose, size and geographical factors were considered in the nature of classification. The benefits derived from FTF migration to CMC are tremendous. It facilitates the exchange of technical, political or social information among participant in a way that is convenient using any of tools of the trade of online communities (i.e. discussion forum, chat systems, emails, skype).
-The classification of commercial online communities dimensions were presented based on pioneer researchers’ opinion. These dimensions were selected from earlier theories of online communities, such that purpose, size and geographical factors were considered in the nature of classification.
+As in any new area it takes time to gather knowledge and develop theories. It is hope that this work will motivate OSN researchers and developers to move forward with more creative design of OSNs without compromising users’ data security and privacy.
