In other news, I've also been trying out Mantis Bug Tracker. I don't have experience with any other bug trackers so I can't really compare them, but this one seems to be really good so far. It was highly recommended on most of the pages I found when I was researching them on Google too. Certainly a lot better than my previous method: the trusty text file!
PS, the new GameDev Store looks interesting, but where are the action figures? I want a Super Mutant Ninja Rhino with kung-fu kick action! And a Tiny Tearful Evolutional that wets itself just like the real thing!
