*: HUUUGE changes animia has been renamed to animone, so instead of thinking of a health condition, you think of a beautiful flower :) I've also edited some of the code for animone, but I have no idea if it even works or not because I don't have a mac or windows machine lying around. whoops! ... anyway, all of the changes divergent from Anisthesia are now licensed under BSD. it's possible that I could even rewrite most of the code to where I don't even have to keep the MIT license, but that's thinking too far into the future I've been slacking off on implementing the anime seasons page, mostly out of laziness. I think I'd have to create another db file specifically for the seasons anyway, this code is being pushed *primarily* because the hard drive it's on is failing! yay :)
