Our org offers series of classes/seminars over several months (academic year). These are not recurring, nor multi-day nor multi-part events, but rather several sessions in a series. There is no way to create a registration form in events that allows people to sign up for the series, either as a whole or for any one or more sessions within the series. We have to do a huge work-around/dance to allow this to happen.

Plus? As I go through this form to submit my idea, "calendar events" isn't even one of the "Area of the Product" choices! I'd love to talk to the developers or managers more about this.
