I'm developing a website and it's closing onto a private alpha/beta phase. It will be exposed to a small selected group of individuals who will provide a fair amount of feedback.
What options do I have for this feedback system? I would certainly like to make it collaborative (excluding email). I could mock up a really simple message board, but would rather use my time elsewhere.
The feedback will mainly consist of feature suggestions and bug reports.
Edit: Actually, would prefer if it's a free hosted service.
