Updated some things recently:
- Added a small navigation box on the homepage to take you to major sections in the Wiki. When there are more articles available, I will work on constructing more detailed index pages with lists of things and short descriptions, instead of relying on the category system for finding everything.

- Added quite a few new articles, and also edited some older ones in order to provide more information.
Pretty much, what's needed:
- More information being added to the existing pages, which will help people better understand and use functionality, for example, more details and examples being put into the Notes section of pages.
- New pages containing information about functions, events, variables and such which have not yet been documented. In order to create a complete resource, more things must be documented!
- Reference materials and tutorials which will walk people through basic scripting stepping stones, and explain more advanced functionality to those who are more competent.

So far, a large amount of the documentation has been written by myself. It would be nice to see some other scripters in the community contributing; it would be appreciated, since lacking documentation is what people complain most about!
