Hi Ben the system is set to log-in every 7 days only. So something may be up with the local browser you are using. I only have to log in once every seven days, can you try it in a different browser and see if you have to log-in daily?
I'll keep a watch on that to be sure it's local to you.
HOWEVER: When you hit the new server today however, everyone will have to log-in fresh and start a new seven day cycle.
