Yes, some sort of RSVP system would be really cool. I guess that would turn it into an event module.....
Maybe there would be a way to ask the creator if the event is one that people can sign up for? I'm thinking of using this mod as a way of connecting members & haven't gotten as far as using it for that purpose, but can see some possibilities.
Would there be a possibility of allowing an admin to create custom fields that people could fill in? Kind of like the garage module? So for example, as an admin I could create text fields for event title, date, time, location, link to map/directions, contact name, etc etc, then a WYSIWYG editor for details of the event. Not sure if any of that is possible, but it would be a great start.
Tagging of some sort would be nice too.
