I'm working on a software app that I will sell online. I'm going to go with the "release-early, iterate quickly" plan, so rapid customer feedback is all-important.
I'm looking for a web app for my site that can handle any or most of the following: forums, feature suggestions, bug reporting, voting on features, release notes, mailing list.
I'm just starting off so I don't need something enterprise level - just something to get the momentum going.
