if you're a Windows user, there's a lot of open-source software available to you. i'm basically a Windows user even though i have friends influencing me to switch over to *nix. i don't think i'm ready for that now. well, for those inclined to use open-source software on Windows, you can check out the TTCS OSSWIN CD, and the OSSWin site.also, you might want to check out Ohloh. came across it while snooping around BlenderNation.
