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. With very few exceptions, you are able to write whatever you want. The creators and hosts of this Wiki, reserve the right to edit or delete information that is offensive or worthless to the objective of this Wiki.
