Just tought I'd post this here.
http://wiki.tockdom.de/
This is a new Wiki created by Tock (the same one that made tracks that work on the 3 special slots and CtockKartWii). Him and a few other people, including Wimms, Vulcanus, BigOto, Chadderz and me are working on the wiki. There's already a page for each custom track, but only 5 actually have anything written on them, so custom track creators please come and make the articles about your custom tracks! We started today, so let's work on it!
