Wiki pages are fun when you have a dedicated and responsible community.

I like restricted wikis best

whats a wiki page

As you've posted, a wiki webpage is like an internet sandbox.. Any visitor can edit the contents/formatting/etc of the page. Some sites use levels like TA (Senior TA, TiT, Custom, etc) to decide how much you can edit, others let everyone freely edit. Its an interesting concept but now that youve posted it here, theyll be getting ridiculous changes for the next few days, I bet.

Try this Link

Then of course there's always http://wikipedia.org/

Threw in my two bits.
