I wasn't unable to log in this morning.
It said my password was wrong, and to wait 15 minutes.
I waited, then tried again (and made sure I typed my password right), but same error.
I even reset my password and got a new one, and waited, still couldn't log on.
Anyway, now I am able to... don't know what happened, but the frustrating thing was that there was no way to post about the problem because I couldn't log on!
Any advice on if it happens again, or why it may have happened?
