[Moose-dev] Bug Model

Hello, I'm Tommaso Dal Sasso, PhD student in Lugano. I was talking with Stef at ESUG two weeks ago, and since I am working with bug reports and bug tracking systems, he suggested me to look at the bug report model in Moose. Can anybody tell me where to find information about that? Since I'm planning a visit in Lille, I was also suggested to ask here to find the appropriate date (I hope this mailing list is the right place). Which period would be more suitable? I think that the best would be near a Pharo Sprint. Thank you! Tommaso
