Event Sign Up

hey there dswd. It is, if you use either the WooTickets add-on (http://tri.be/shop/wordpress-wootickets/) or Eventbrite Tickets add-on (http://tri.be/shop/wordpress-eventbrite-tickets/). They both allow you to have ticketed events, and if you offer free event tickets to serve as an RSVP component, it’d accomplish what you’re going for here. It isn’t doable with the core plugin on its own at this time, though.

Hope that helps. Let me know if not and I’ll try to elaborate best I can.
