We are currently still using the svn repository on Novell Forge. We are waiting for the Codeplex team to implement merge functionality and then I will test it again. I'm not testing at all with their TFS client, as I need it to work with svn so linux developers can still access the repository. Probably another 4 weeks or so before they finish the merge features.
We are releasing files on Codeplex already http://www.codeplex.com/mojoportal and we have an Issue Tracker there that can be used for more formal bug reporting than the forums.
If/when they get the svn bridge working well enough for us I'll make an announcement in the blog about the repository change after its up to date.
Best,
Joe
