We have a client, a non profit association, that like us to build a tool for them to communicate with all their members (up to 500) . They like to keep them as close to their ecosystem as possible, interested to engage, hence the need to show their own identity.
If we can get it working, we have another one that has 20.000 members that currently uses an old social network we developed 3 years ago.
We are still not sure if MM is the best solution.... but we I start to feel it could be perfect if this could work out
