The Forum plugin is a great way to build an online community and support collaboration across the Internet or on a local intranet. You can create categories to organize conversations, create discussions, post messages, restrict forum access, and even convert glFusion stories into forum posts.
Before using the Forum plugin, you must create at least one category to organize your forums. Once a category is created you can add a forum to the category, where people who have the proper access rights can read and post new messages.
The Forum plugin also supports the glFusion security model, so you can easily restrict access to any forum or a group of forums. You may have a specific forum setup for site moderators to discuss issues and users. You can easily restrict access to this forum to only the defined moderators.
Another great feature, if you have created a few stories on the main page, and people have left comments in them, you can convert those stories into topics, and the comments into posts!
