Welcome to WebmasterWorld Guest from 188.8.131.52
I like how they have you suggest 3 new sites for the category you are interested in becoming an editor for, and then they seem to ignore you. I even wrote them twice, once to a category editor, and once via the complaint form, and I still haven't heard anything.
Oh, well. I guess all of the other marketing gurus have taken up the good spots, and they don't feel like letting me join up. Good luck though, if you get in, could you drop me a line/plead my case? I'll give you the email I used, if you drop me a line in the stickymail.
