I didn't get any satisfying answer about the Bug Goo used by tla. I don't think it is ready to be usable by another project. (No administration manual, evolving quickly, ...)
So, I think the only candidate is the gna.org's bug tracking system. I suggest we start using it little by little. Stefan, you're the project admin, can you configure it to send an email to this list whenever a comment/new bug is posted? Or do you think it is better to create a separate list xtla-el-bugs? -- Matthieu
