We have a SimplePress site with distinct user groups. We do not want a user in group A to be able to message a member in group B (unless the user is also a member of group B). Currently in the messaging interface, users can message each other across group memberships.
We could set the site so that the messaging system only works via the “PM” link on a post, but that’s inconvenient for users.
Is there a way to restrict messaging in this manner?
Thanks!
