What is a wiki?
A Wiki is a special type of web site that enables a group of users (in this case, anyone on the Internet) to collectively edit, expand, revise, and create content. A Wiki is particularily useful when an exploration into a particular area is desired. A collection of authors will often reveal and devise content that any single user cannot.
To edit a page (even this one), simply click the "edit" link on any page. If your post is blocked by a Spam Filter, read here why this happens: Website_Participation
