If you need a wiki for your game, I'm your guy.
If you don't need a wiki for your game, I might make one anyways. (unless you want to keep things secret, of course!)
Basically, I just do a lot of wikis. (but I am working on my own game!) I also love to talk about fangames in general. A fun direction you're taking your game? Anything you're curious about with mine? Someone else's fangame that you just really like? Let me hear it!
