I must be completely stupid, but I can't seem to create a special page for mediawiki 1.5.8 following any flavor of the instructions on Meta - Help!!!
On another note, I had previously been all excited about this theory that spam would tend to be a lot of urls posted in a wiki (or accross several wikis) and that posts of individual urls would be more likely to be legitimate. After mangling some data (an long overdue thatnks, Brion, for the link to the catpcha log data) I quickly came to the conclusion that this theory wasn't going to be useful - plenty of spam of one or two urls, and some mulitple posts of legitimate urls. Oh well... the captcha thing is a great solution though.
So, if someone could steer me in the right direction on the special pages, I'd be very grateful.
Thanks, Aerik
