One common aspect to many successful teams I see is that they use some sort of knowledge sharing and open discussion platform instead of a forum.<p>What forum/wiki/project tracking software do you use to share professional knowledge?
We use Redmine <a href="http://www.redmine.org/" rel="nofollow">http://www.redmine.org/</a> - works well, nicely integrated with wiki, issues, repository browsing. Wikipedia overview: <a href="http://en.wikipedia.org/wiki/Redmine" rel="nofollow">http://en.wikipedia.org/wiki/Redmine</a><p>Chiliproject <a href="https://www.chiliproject.org/" rel="nofollow">https://www.chiliproject.org/</a> is a fork of Redmine. I have done a test install but not used it seriously.<p>I've used Trac <a href="http://trac.edgewall.org/" rel="nofollow">http://trac.edgewall.org/</a> also. I like Redmine better because it has (or had, have not checked lately) better multiple-project support.<p>Our "front office" folks use Alfresco <a href="http://www.alfresco.com/" rel="nofollow">http://www.alfresco.com/</a> but their use of it is almost exclusively as a Microsoft Word storage shed.
