VASoftware which powers sourceforge.net has an enterprise edition that has a free download with 15 users. For more users than that it's a one time fee of about $1000/user + 20% annual maintenance, but if you have a small team, 15 users free forever seems nice and it has a lot of nice features (document management, feature/defect/anything tracking, task management, release management, source repositories (cvs or svn)). You can find it here. David
