just realized this problem, when a user tries to register and fills up all the boxes in the first sign-up page and clicks next its all good, but once it goes to the second part and selects the URL and name and clicks on the 'signup' button wpmu sends the user back to the first page claiming the emails were different/incorrect/not matching.
Anybody has a lead on the problem? tried updating but it stills the same.
