Might I also suggest that if you keep it you protect the main page of your wiki? (or only allow logged in users to edit it). I just went to the page and was greeted with an angry message containing a profanity... (I've reverted that change with the history... but, it certainly wasn't a very good first impression).
That being said, I agree with the previous posters that already existing wikis (like
FIRST Wiki or to a lesser extent Wikipedia) are better suited to serving the FIRST community in general (though, for TechnoKat specific or local information it may be useful for everyone to have editorial control).
