I can't sign up. I really don't like the tiki interface either. i would much prefer that the normal wiki interface be used.
I hope nobody minds, i edited the wiki here:

So people can start putting their shows up.
There's no excuse now! When DJquad puts a mediawiki on katg.com we can just copy over all the posts, so you may as well start now!
