I'm a little surprised that this Shakespeare Wiki has existed since Feb 2006 and I've never noticed it. It looks like it needs a little help, all I see are Character summaries and even then a bunch of them (like The Tempest) are empty. The page says it was last modified Oct 2006. For a minute there I was hoping that it was a typo and that the site really had come into existence in Feb 2007 a mere month ago.
So there you go, folks. If you've ever wanted to contribute some Shakespeare content but feel overwhelmed by the encyclopedic amount of info already in Wikipedia, here's a place where you can start fresh.
