Hey people!

Does anyone know a good Bug/Issue tracking system. Best: OpenSource / without cost, but usable in a educational enviroment. If not, what, other that JIRA, can you recommend from the commercial side?

Thanks in advance.

(Yeah, I know, this isn't a Linux issue, but it's kinda "openSource-issue" which might be okay here.

I might x-post it to some other communities.
