I'm trying to figure out how to structure my forum for forum leaders who want to offer classes. I'm trying to find a way where their classes can exist on the actual forum via videos, attachments, etc. However, is there a way for people to pay for each of the classes without having to leave the site other than perhaps going to Paypal? In other words, I'm trying to figure out how to "rent" space on the forum for people who want to teach classes within the forum (rather than taking people out of the forum).
Would love to hear of anyone doing something similar or how it can be done technically.
