Jason Zander on the WinFX to .NET FX 3.0 rename

A question i didnt see answered, yet i think its very important.
What does i require to use codeplex? The team explorer is a VS team system only feature.
But seems like you can download the team explorer from their site(?). So would this work in express too?
Very interesting stuff and I look forward to it being opened up a little more to more project... at the same time though I'm kind of puzzled.
CodePlex sounds just like GotDotNet with a Team Foundation Server backend.
Rather than build another Windows/.NET community coding website... why weren’t the new features and backend built for CodePlex used to create a new GotDotNet version but still use the same name and avoid the potential rivalry issues.
