I am getting a lot (over 100) of users trying to register but it does not complete. I have it set to confirm email so I'm guessing they are not confirming that. Is it not very straightforward or is this common? Also, most users, even if not signing up through Facebook, are having their full names as user names. I've tried to ask a few and they've said they wanted me to change it but haven't been able to indicate why it populated as their full make. Is this common also?
