Forums are extremely popular methods of product support for both commercial and Open Source applications. In fact, the Joomla community thrives because of the forums (forum.joomla.org) that cater to both Joomla Web masters and Joomla developers. This forum uses the Simple Machines Forum (SMF) application to provide message-posting services.

Message boards predate the Web in the form of an electronic Bulletin Board System (BBS), the most popular among them probably being The Well. When the Internet began to grow, the Usenet “distributed Internet discussion system” gained prominence. Now, Web-based forums can be easily incorporated into an existing Web site or Joomla system.

Simple Machines Forum (SMF)
The Simple Machines Forum (SMF) is the forum component that is used for a message board on the central Joomla site (www.joomla.org), so it has proven its ability to sustain great amounts of traffic and continue to perform well. The application is available in more than 20 languages, including English, Albanian, Arabic, Swedish, Catalan, Persian, Chinese, Finnish, Greek, Japanese, Turkish, Portuguese, French, Dutch, Spanish, German, Hungarian, Hebrew, Bulgarian, Italian, Thai, Polish, Russian, Norwegian, and Romanian.

Online chat can mean anything from a traditional direct chat room interface to the newer Shoutbox implementations that add instant messaging (IM) capabilities to a site. In recent years, chat features have gained a somewhat dubious reputation because of their use by predators who seek to lure underage participants. Not a week goes by without some news feature or investigative piece airing on television that describes some villain using a chat room for bad purposes.

While a huge majority of chat rooms are certainly not dens of iniquity, the problem is significant enough that you should give it serious consideration before adding these capabilities to your site. The immediate interactive nature of an online chat makes it much more likely to be abused than other technologies where interaction is non-instantaneous and, the interaction is generally posted for the entire world to see.

You should also know about the legal implications if a bad person were to use your site for some form of crime.

A guestbook is one of the oldest forms of Web interaction. It allows visitors to post commentary and compliments on the contents of the board. Although a guestbook has little implementation cost in terms of time and energy, it also inspires the least community spirit. Therefore, a guestbook is a better addition to a traditional Web site than it is a feature used with most community sites.

The two most popular guestbook extensions for Joomla are Easybook and Jambook. Since a guestbook is fairly simple in both conception and implementation, these extensions provide very similar features. Your choice will likely be dependent on which extension most appropriately compliments the visual aspect of your site.

Easybook
Easybook is an excellent simple guestbook component. One of the best features of the component is the extensive anti-spam protection such as CAPTCHA (Completely Automated Public Turing Test to Tell Computers and Humans Apart) image generation, live email address confirmation checking, and automated word filter. The word filter list can be defined through the Administrator interface of the component and configured to automatically send an email to the administrator if someone attempts to post an item on the prohibited word list. Easybook can also be set to ping the supplied email server of the poster and ignore the post if the server isn’t valid.

With all of the difficulties in running a virtual community (mostly in added workload and time), it might seem to be a questionable undertaking. This is not the case. I am not trying to discourage the adoption of virtual community technologies but simply make you aware of some of the challenges in their deployment.

The greater your knowledge of the challenges before you attempt to create a virtual community, the greater the likelihood that you will be prepared for the difficulties and overcome them. A poorly implemented community is much more likely to be a failure than a poorly implemented Web site. The Web site will still garner visitors looking for the information it contains, while a failed online community will be like a ghost town with few tourists.

Despite any disadvantages to creating a community, the benefits are substantial:

Creating a virtual community is somewhat like making a movie. Before a single camera starts to roll, there is an entire process of preproduction ensuring that the actors are properly cast, the equipment is rented and functioning, the script is in place, and the department heads know what type of movie they are trying to make. If any of these areas are neglected, from the first day of shooting, the movie will stumble forward, and a vast amount of time and energy will likely be wasted.

Likewise, a virtual community is expensive in time to launch, difficult to attract visitors/contributors,  and poorly planned execution will make even a promising start fizzle into a disappointment. Although Joomla makes the deployment of the features simple, proper planning even for an incremental deployment is critical for site success. By being deliberate in your planning and construction of the new community site, you will minimize the chances of hard-won users becoming frustrated with a poorly working or confusing roll- out and leaving your site forever. The creation and deployment may be divided into roughly three stages.

Three Stages of a Virtual Community
Virtual communities are unlike most traditional Web deployments (such as a static site or online store) in that they derive their value from the intercommunication of a large user base. Under any circumstances, gathering this large number of users can take quite a bit of time. The creation of a virtual community is typically a gradual process, and a visitor surge does not provide the benefits it would on a traditional site. If your Web site was suddenly flooded with a million users overnight, it is unlikely that the site could retain those users for more than a short period of time. Furthermore, the first experience of these new visitors would be empty content and slow performance. Growth for virtual communities is organic because the community slowly discovers what the group has to offer.
