Getting Started is as easy as diving headfirst into the wiki.
Realize that this information is going to be in the public domain and therefore it most likely will be mercilessly edited and changed over time.

If you're not sure what to tackle first take a look at our Most Wanted Pages and knock out a few of those. If editing is more your thing look at our cleanup required category to see what existing pages need another coat of polish. If you still don't know where to go try a random page and follow the first red link you find! There's plenty of room for improvement so get started today!
