This site runs the MediaWiki software, the same software which powers Wikipedia. It is easy enough to use that anyone can contribute, and because every single change can be undone and inspected, nobody should fear making mistakes.
Here are some useful links:
- The User's Guide is the complete reference for users of this software.
- Editing Help will give you the basic of how to edit pages. (This link also appears at the bottom of the page every time you edit something.)
- MediaWiki FAQ
For the technically-minded who want to know about administration and tech issues:
