Hi Rebecca & Tod -
Sorry for the problems, and thanks for trying to get onto the new forum.
The problem was definitely at our end, and I have corrected the error. There are likely to be a few bumps in the early going (since the forum is completely new software written from the ground up), so thanks for your patience 
I should also add that any bug reports/feature requests on the new forum are greatly appreciated, as they can only help us improve the service.
