I'd like to have a way to use eCal or AM Event to allow people to register for scheduled events. Maybe even put a maximum registrations allowed for each event.

i.e. I add a new event and indicate by checkbox "Allow registered (xoops site) users to register to attend this event" and a text field that allows me to indicate the number of registrations before the event is full.

Obviously a later modification would be to allow a waiting list. And maybe have the calendar itself show somehow the event is full or open still.

Lots of ideas in this area... maybe one of you gurus could whip this up in an hour or two? ;o)
