This site is a Wiki. It is based on MediaWiki, the same technology that underpins Wikipedia.

WikiWiki is Hawaiian for "quick". The original idea of WikiWiki was to create a collaborative, fast environment which would still be persistent.

The key is that as many people as you like can contribute. All you need to do is login. Yes, you can delete what other people said, and even delete whole pages, but surprisingly, wiki does work.

When editing, you can easily create (and you should create) hyperlinks by just putting the word in square brackets, [[like this]]. If the page you are referring to does not exist, the resulting page will show in red. Like this: dummy page. (Please don't foil this example by creating that page...)

Wiki is and should be simple. This is why there is no need for complex HTML. You can get some effects, such as bold text and italics, but nothing very complex. Layout is looked after by the Wiki itself. There is more information in Help:Editing.

If you do a Google on Wiki you will find it is a growing collaborative social phenomena. For example Wicked (Good) Wikis. Blame Rick if you don't like the whole idea :-)
