On my few tries, I had difficulty in changing my password in this forum so I decided to be proactive and do something about it. 
Here are the steps to changing your KS Forum password:
1. Log into your account using old password
2. On the top left corner, where it has "Welcome," click on your username
3. You should be in your profile page now so click the "Edit" tab on the upper right side
4. Go to bottom of the page, to the Password section
5. Enter your new password... twice
6. Click update profile
and that's it, you have your new password!
