I had no problems using my new password.
Does the forgot your password option involve emailing you a new password?
No, it does not.
I am 100% sure I didn't miss type it. It constantly told me my password was wrong. And as I said, I used the exact same password yesterday without any problems.
The password was created directly after the second time the forum was back and running.
The chances of you making a mistake are much higher than a new password being bruteforced in such a short period of time.
