Uh... I hate to plug my own stuff, but it directly applies.

Why not use [StackList](https://stackapps.com/questions/936/stacklist-list-your-apps-track-bugs-and-more) for this?

It has an integrated comment / bug management system... and you've already listed your app [there](http://stacklist.quickmediasolutions.com/view_app.php?id=32).
