Sometimes I create message board accounts for folks, and I assume they may like to change their password, and sometimes a body just wants to change. This is how to do it:
First log into your account.
From there you should click on the "User Details" button near the top of the window.
Next, on the left under Profile, you should click on the Edit Profile text.
From there all you need to do is type in a new password, and make sure to hit the save changes button.
