We developed an event registration system a few years ago that we could share if it you're interested. It's a Java web app and thus requires a Java servlet container such as Tomcat. We've never shared it before so I'm not sure how much effort it would take for someone else to get it up and running. You can create events that have one or more occurrences. It allows for registration, registration caps, and waitlists. Reminder email notices can be sent automatically or manually. Event maintainers can view and manage registration lists, mark attendance, and add walk-ins. A couple of limitations it has are (1) the basic model is things like workshops that begin and end on the same day -- it's not really designed for multi-day events or conferences where people can register for different tracks, etc., and (2) while it can maintain waitlists, it does not automatically bump people on the waitlist up to registered if a registered person cancels -- you have to do that manually. Anyway, I imagine that there may be simpler solutions out there but, if you don't mind running a Java web app and being the first to try to install our home-grown solution elsewhere, I'll be glad to talk with you further about this option. --Jim Coble [log in to unmask] Duke University Libraries
