Hi,

I have some problem. I'm trying to allow registered users (those from specific group in security tab) to subscribe/register to calendar event. I want also let the administrator to check who is registert to given event thru CMS.

I'm already trying another aproach. I tried some and failed.

My question is how to modify calendar modul in such a way that when date of given event expires some of the event data changes.
For example if event has registered users as $many_many relation, then empty this relation when date expires.
