class registration

Hi,

I'm building a site that allows people to announce various classes and events. Ideally I would like for people to be able to enter the dates that registration opens and closes for the class on the same node/add form they enter the rest of the event information, and then have something like "XYZ_Class registration opens" on the day registration opens and "XYZ_Class registration closes" on the day it closes, and have "XYZ_Class" listed on the day it happens.
