Project Management Tool (Collaborator)

This is a good Project Management Tool I have seen so far.

It also has a vast list of extensions to plugin with other components, like Documentation (wiki, twiki etc), Bug trackers (Bugzilla, Trac etc), Calender func for Time tracking, Repositories (Mercurial, GIT, SVN etc), Diff viewer for the code, Code reviewing components etc.

Just have this in your env, you dont need to jump around multiple links for collaborating between PM to Dev to QA to Customer Support team.
