I just heard that the problems we were having with GotDotNet have been cleared up.  If you had trouble downloading the MSF Agile preview docs last time go to http://workspaces.gotdotnet.com/msfv4 and try again.

If you had a pending membership that didn't return, it should have cleared the system by now.

We've opened up the workspace, so you don't need a membership to download.  You will need one to post comments in the workspace area.  I hope you will give us some feedback!
