I'm collaborating on a project where I'm starting to feel the need for a shared issue tracker. Anyone have any suggestions? I have my own server (running ubuntu maverick, so pretty up-to-date), and can install pretty well whatever I want there. I'd love something that integrates with org-mode somehow, but my collaborators are definitively NOT emacs users. I just started a project on google code, but that doesn't seem quite right -- for one thing, we're not _really_ doing much coding, and for another ,some of the issues should contain private notes -- e.g. phone numbers and emails of people we need to ask for help or information. It wasn't immediately apparent to me that privacy fetures like that exist on google code.
