Not listed: the offending description, on which the whole thing seems to hinge.

Meetup.com seems like an awful choice for conference registration, or any one-off kind of event. I've been running not-for-profit tech conferences for a few years, and the mix of Eventbrite for registration (especially if it's a free-to-attend event, as mine are), and Lanyrd for schedule, speaker, session listings, and social interaction have turned out to be the perfect mix for me.

The only thing I'm missing out of those two is a system for accepting and voting/choosing speakers and sessions, but hey, I'm a developer, there are ways. :)
