I’ve been using JIRA to manage a project and it’s my new favorite tool for distributed team game development.  It manages code, tasks, bugs, secure svn, and all of it is integrated pretty seamlessly.  It’s got support for Agile planning (aka. SCRUM) which is really handy.  It’s also got a Wiki for sharing design docs.  It’s presented in a web view accessible over the internet.   This definitely beats using Google Docs and DropBox, which I liked for small team projects before trying this.  For a micro ISV, it can take care of some of the development related IT stuff.  I’m not sure yet how well it scales for larger teams.  For more info on JIRA, check out their website here.
