500 is probably on the conservative side for you Bert:-).....For the record we've received over 1200 requests in the last 14 months. It's increased substantially since we've been encouraging users to contribute suggestions, many users were not aware of the option under HELP.
By the way, of those 1200 very few are the same or even close. Some yes but just a fraction and I'm talking about a couple dozen here. However that simplifies our prioritization process as we focus on those we see most frequently.
David I'm not aware of performance issues with the Reminders but Support may...they should take a look, as Bert suggests it could be environmental.
