It's actually a really quick and simple process! Changing your password will take affect on both your in game and forums accounts.
1) Click on "Profile"
2) Hover over "Modify Profile"
3) Click the first option
4) Type in new password exactly how you want it to be spelled
5) Reenter your new password
6) Enter your old password into the final box at the bottom and click save
7) Log out and log in through the forums*
8) Log out and log in through the game*
*If these steps don't work then contact Ryan, Danny, or Billiam any way you know how to try to get your account recovered.
This is really helpful, some people out there don't really understand how to use the forums properly.
