The client currently uses Event Espresso for their registration framework which has (2) must-have features:
1. paypal confirmation (on the backend they can see who has successfully paid and who has not)
2. ability to copy events
It looks like #2 is "kind of" possible with 'recurring' events (https://premium.wpmudev.org/forums/topic/ability-to-copy-or-add-another-date-for-same-event), but only for recurrance. The 'Add another event date' option does not actually create a separate event, just a 'part 2' so there is no tracking of RSVPs for it.
So, in sum,
Q1: any update on the COPY feature for events?
Q2: how can I tell if an RSVP has PAID or not?
