Just read that Microsoft has launched CodePlex. It is a development community where you can start projects, work on them with teams, use RSS and WIKI pages to communicate, and most impressively (if I've read correctly),use a Team Foundation backend which will integrate into Visual Studio. Now that's what I am talking about. I like your everyday sourceforge sites, but I do not like CVS, RCS or SourceSafe for that matter. I'm hoping this will integrate cleanly into my favorite tool for authoring code.
