Hello,
I re-read the documentation https://docs.corejoomla.com/Configuring_multiple_profiles_in_Sociable but I ask if this will not duplicate my vision which is to manage members and groups 100% Joomla!?

You may have understood my approach with my previous questions but I will not be in the simple configuration with 2 groups (students and teachers).

I want to create (in the medium term) dozens of private Sociable groups (1 Sociable group = 1 ACL joomla group).
I understood that I must have a Sociable unit group but then what do you advise me?

Regards
