Bots like to register for the wiki a lot.
They register then post.
I suggest seeing if you can integrate with this forum's tables (you will have to re-assign the sysop positions) or add some custom line to the registration. For a while there, I had one that asked what 2+2 was and if anything other than 4 was there it gave and error who's string didn't even exist.
Just wanna try to warn you of some things I've learned by having a wiki myself.
Deal with it as it appears probably, if it becomes too busy then might get CmptrWz to implement a simple captcha of a sort (like what is the square root of -1:).

I decided against linking it to the forum for a few reasons, including me being lazy. As for a captcha system, I may get to that sooner rather than later. Given how new the wiki is I should have a few days before the bots even find it, let alone start trying to hit it.
Any thoughts on the current Captcha? I can revert it to simple match questions without pictures if you think the current one is too difficult.
