Here is the deal: we don't have a fancy bug tracker setup.
But that's OK because this site can easily be used for bug reporting and tracking.
All you have to do is to post a new topic, not necessaraly in the form of the question and just tag is with a tag 'bug'. you can add other tags, but one of the tags must be 'bug'
That's all it takes to report a bug. I monitor this tag so I'll receive notifications of new bugs.
Other developers may follow the 'bug' tag or can follow any of the specific bugs. The reporter of the bug is automatically follows own question, so will be automatically notified when answer or comment is added.
I can then add comment if I need more details or can add answer. I can also close the bug by just closing that question.
Nice and easy and this just shows you how this type of program can also be used as a replacement for a fancy bug tracker.
