I have had a few problems reported without an email address included. This is usually OK, but sometimes I need more information to identify the source of the problem. If you reported a problem, but did not receive a reply and the problem has not been fixed, please resubmit your problem and provide an email address.
Is this happening to you? If you see every event twice on your calendar, let me know if you are willing to share your calendar with me. Seeing the problem will help me find a solution.
