I would say something simple available on Github is enough. However, I set up Trac on my server and the few programmers we had used it crafty enough for it to help. We set up milestones for deadlines for specific assignments and used it as a webpage where we could look at all the commit activities. I'd say that teams should move to Git or Hg (Mercurial) and use Github/Bitbucket which both have good web interfaces for very basic, but useful, issue tracking.
