Hi guys! So I'm trying to figure out how to add all registrants from a particular source to a group during registration. I'm launching a new eBook to help kick off my forum, in a few hours. And I'd like all those registrants to be tied to a specific group. I plan to launch a few eBooks over the coming weeks - so each time I want to keep track of what product someone bought to get in... and give them access to a private forum specific to their purchase. Any ideas on how I can manage that? Thanks! Bolaji.
