Just so folks know, we expose the ability to cancel the premium version of Get Satisfaction right within the admin area. If you'd like to cancel, just follow these steps:
1. Click on "Admin" in the grey Community Toolbar at the top. Note you must be an admin to see this option
2. Click on "Account Details" from the options on the left
3. Scroll to the bottom of the page and click on "Want to cancel your premium account?"
You'll also have the option to enter a reason for why you canceled before you confirm.
