- I knew I forgot something...

- That'll come with #1.
- Bit more work, but can be done. (Was actually planned for version 1.1)
Right now, the AdminCP interface is being constructed, once that is complete, I'll release version 0.91 (RC2)
If all goes well, version 1.0 (with some serialization to collect information from users that register) will be released, along with me starting to work on version 1.1, which will include calendar integration, customizable information collection, and perhaps even seating charts... Although the charts might be a bit extreme.
I could integrate this with the "paid subscriptions" part of vB to allow people to pay the registration fees through Paypal during their registration, but that will have to wait until 1.1... Until 1.1, the admin will have to deal with payments on their own.
