Questions regarding the White Scenarios board are best directed at the White Scenarios board, since it operates somewhat independantly of the rest of the Combine. I'd suggest, though, that you sign up with current handle and can edit it later. Handle in training over there is primarily to track people, since you won't get XP or CP or anything for completing the training.
In actual Scenarios it's a little different, since XP is awarded.
