It shouldn't be! No site is 100% secure, so if someone somehow got into Proboards system and took the passwords file, it would be very easy for them to put 2 and 2 together and try to get into your mTurk account. PLEASE change your password here if it is the same as on mTurk by clicking here.

Update: we've had users attempting to hack into accounts to gain access to the hidden forums. If your password is "password", "123abc", or something equally simple, PLEASE CHANGE YOUR PASSWORD!
