The new RSVP site is a private site I built with RSVP-to-Me, using a local database that is not shared or sold with anyone. No account necessary - simply use your email or phone # for a confirmation code the first time, then again every once in a while. Every free site I found out there had too much compromise, and every paid site wanted ludicrous amounts of cash per month, so I finally hunkered down and built my own.
