A user plug-in pp CB that shows \"my attended events\" and the possibility to cancel the registration.
If you go to an event and you are already registired for that event you should also get possibility to cansel registration.
Today it is possible to register MANY times on the same event..
Registered user i CB have an ID but unregistered users should have a uniq email and/or name
We already have a CB plugin that shows your registration history, and DO have plans to soon and the ability to UNregister from there.
Regarding being able to register many times, we also have a setting already where you can disable duplicate registrations which checks by email address and will not allow that email address to be registered again for the same event.
This is important, especially for FREE events, where you need to allow people to cancel in order to get a better count, but it is also good for paid events that allow early cancellation.
If a logged-in registered user has already registered for an event, it would be nice if there was a CANCEL REGISTRATION button on the registration page. This would just change the STATUS on the registration to CANCELLED, and if refunds are owed, that would be up to the event manager to handle via looking at the registatrion details.
