We've added a new feature to MyUFP, which is located in your UserCP. You can now view a history of your Roll Call signing, beginning in April 2012. It will expand to eventually show the six most recent Roll Calls, but for now will only display the two Roll Calls that were handled via the new automated system.
You can view your Roll Call history by going to your UserCP, and selecting "Roll Call Status".
Hope you enjoy!
