Forums are online discussion groups. A forum is generally set up like a series of long chain emails. The forums are divided into several topic areas. And within those topics areas people post area specific material. If you are reading a particular post and wish to add to its subject you simply "Reply". By "replying" to the post you add your post to the bottom of the discussion or "thread" A forum can contain several threads of conversation. When you enter a forum, find the thread that best matches the message you want to post to the forum. If register as a member, you can start new threads or add to existing threads.
Registering is easy, and a very minimal amount of information is required. You can choose to hide your email from the public, or if you are terminally paranoid set up a new google gmail or yahoo mail account and use that to register.
The forums are a great tool for team problem solving. They've been around the web before web browsers (you may also hear them called Bulletin Boards or BB for short) they are very effective customer support tools. People post problems and symptoms on a board that is appropriate to their issue, and they wait for people to reply (this creates a thread). There are forums for almost every topic or hobby imaginable.
Our forums have several topic areas. There is a general area, a suggestion area, a technical support area, staff only areas, and several specific discussion areas like: Letters to the Mayor, Think Tank, and Letters to Council. Topic areas cane be created, modified, and deleted by the forum moderators and administrators.
There's a lot more to using forums but this is a quick and dirty just to get you working post. So PLEASE use the forums at http://eastonundressed.org/cgi-bin/yabb2/YaBB.pl
