I'm interested if any of you have any ideas/criticisms on how this site looks.
Personally, I don't care too much for the color scheme and it's excessively plain right now (though, that may not be a bad thing). To be honest, I don't have a very good eye for these things anyway. One of my first thoughts is to replace the "Frets On Fire Wiki" with a better-looking picture, perhaps done in the same way that the forum's logo was done.
There's plenty of control on how everything is laid out (CSS), so really, almost anything can be done. Right now, it's one of the preset "themes" that I made some small modifications to. Some ideas can be had from other featured pages on the Wikidot home page.
