Hi Tuan,
that sounds great. I've been thinking about this issue for a while, and have some suggestions/requirements, so that it would work for me.
As a reminder of our setup: We run terms of clubs (14 events). People sign up for a term. People can sign up at any time (if there is space), and just pay for the remaining clubs. At the moment, I manage this (changing dates, shared registration lists and reducing cost) by simply having 1 event for a term, and then updating after every event to reduce the price and shift the dates.
1) If people register for the term, we will need to be able to easily cancel a registration for all term events as well.
2) For each event, I'd like to set up a list of children events, e.g. after clubs 1 and 2 have been completed, if somebody registers for club 3, they are registered for clubs 4 through 14 as well, and only pay price of club 3.
3) If the next event is Club 2, and somebody is looking at the calendar of all that club's events, and click on, e.g. club 5, then they should be redirected to Club 2 for details and to complete registration and payment.
4) In the category list of events, I would only ever want the next event in that term shown.
5) For book keeping purposes as well of management of lists, we would need to discern between a real registration, and the automatic registration for children events.
6) It would be great to be able to use the lists to check in members each week.
