Is it possible to assign a group on registration based on white-listed domains? I ask because I have a unique use case. I need the ability (without having 2 instances) to direct traffic to one of two groups, depending on what they use as their registration email. I need one group to be able to participate in a discussion in Forum A and only view Forum B. I then need the other registrants to participate in Forum B and only view Forum A. I can't figure out an easy way to do this (manual group assignments after registration would be a nightmare).
If anyone has a suggestion on what I could do, I'd be open to hearing about it, and I can share more information about my scenario.
