You can sign in to UF with your account username or email. I'm not exactly sure how signing up through Facebook works (I'd assume it takes the email you used to sign up with Facebook, etc), but you can check the email you have your account listed under in your
account contact details.
If you have an issue with your login details, please contact an administrator first. As stated,
multiple accounts are strictly against our rules.
Locking this thread now, not really necessary to keep discussion on this going here.
