Community Server 2007 SP2 was recently released. I suppose I should upgrade soon. But I am moving away from CS because of Telligent's licensing scheme, and the continued lack of some features that DotNetNuke offers. While CS is still faster than DNN, it also lacks many features - one still has to dig into templates far too often. But mainly its the licensing that has me rankled. You can read Minh Kha's post on the topic which gives a pretty good summary of my thought as well.
