Seriously. It takes 0 effort to make a SMF forum. I'm sorry, but it doesn't. The most impressive thing on here is a homepage, but that may or may not be just a plugin. I believe I've seen this theme somewhere near the bottom of the SMF "reccomended themes" board. I dunno about the Tiki Wiki. Judging by how it's nowhere to be found in the actual forum directory, I can assume that is using some other software fitted to be similar to this.
Feel free to correct me, admins.
(Excuse me for a second.)
