Samuel B,
Thanks for the response.
I installed contact form 7. It allows custom forms, but it is really a one way form of communication. I would prefer something like an editable spreadsheet that is instantly updated (maybe after a change is approved by a mod)this way 20 people don’t register for the 8-10 timeslot, and no one registers for the 10-12 timeslot.
Any suggestions along that line of thinking?
