I’ve tried to get people to use Evite and Upcoming with limited success. The former is too cutsey, while the latter is cluttered and requires a Yahoo! account. People resist completing a registration when they fail to see the value in whatever they’re signing up for. For many, an online RSVP service is questionable.
Mobaganda is as simple as can be. All you must do as the organizer is list your event. All participants must do is enter an email address and select “Will Attend” or “Will Not Attend.” Couldn’t be simpler.
