I am wondering if anyone knows of any software that will handle online registrations (perhaps through a sql database or anything else)? I want to create an online form for people to fill our and register for several conferences (but wish to assign a number limit for each conference, so for example, Conference A has 50 slots available, after it fills up, it will be taken off the registration list) I have toyed around with OScommerce before, and pretty much was hoping there is something like that available.
