[Send Automatic Reminders to Event Registrants]

I would like to be able to send an email to everyone who has registered for a particular event (for example, a reminder email 2 days before the event). I can see how to schedule calendar emails and send a list of events within a particular time period, but not one specific event. Within the event information, I can't see how to send anything but an invitation.

Ideally, I would like to be able to send an email to the registrants without having to add them all to our address book - we have so many events that even with sub-groups, the address book will quickly become unwieldy.

[RSS feed customization]

I've read the help page on customizing RSS feeds, and I'm still unclear - is it possible to customize the default feed, or only to create additional customized feeds?

[Event Activity Reports]

I saw in the Trumba Help Center that you can view activity reports for published calendars. Where do I locate this report?
