MyBB Hacks

Hello guys! I wanna know how can I crack a mybb forums' password hashs according to the uid. Any help? THANKS!

Enter 'a' as the password.  If it doesn't work, try 'b', and if that doesn't work, 'c'.
If you run out of single character passwords, try two character passwords, then three etc.

Given enough time, you'll recover the password.
