I finally upgraded the blog to Community Server 2.1 SP1 today - its been out for a little while but did not get the time to upgrade till now. Everything seems to be running fine, but if you find something broken then let me know.
The next version of CS , does have lots of code-names, but I don’t know what to make of it. It is supposed to be out sometime in Q1 07.
Update: I found out some more information on CS 3.0
