Second attempt ;-)
I still miss the feature to treat a set of events (recurring) as ONE event with of 10 units.
People register for the event and its full set of event dates, not just the first (as now).
To improve it even more, it would be helpful to also monitor attendance of each of the event-units (the recurring dates of the recurring event). I mean, that attendees can easily manage (through ONE table, not by clicking through all the evtn recurrenses) the days they can attend where they are uncertain and where they will attend, similar to DOODLE.COM.
What do you think ? Who is with me?
