WHY HAS MY USER ACCOUNT BEEN LOCKED OUT? HOW DO I UNLOCK IT?

After entering an incorrect username/password combination three times, the user account will be locked as a security precaution. 

Unlocking your account is just as simple as resetting your password. Click on the “Trouble logging in?” link and select the appropriate option in the drop-down (Unlock account). You will then need to enter your username when prompted and you will be sent an email to reset your password.
