We have a potential client that the “make or break” point is being able to have members in multiple groups.
The reason is not for any “security” reason, but for communicating to them. We thought of using the “Communicate” module as this would accomplish quite a bit, except…
They may have a customer that signs up for three of their programs. Think of these programs as member groups. The member would need to be in all three “programs” (aka, member groups). Obviously the Communicate module can send email to specific member groups, but there is no way to put the member into multiple groups.
Any ideas on how to accomplish this either natively or with a third-party add-on? The key is the ability to email the members.

However, the Communicate module does not allow you to email “categories”... only actual member groups.
