I wish MM supported multi-site layout and also could add multiple MM plugins on my own without having to contact a MM support admin to activate them. I run many different sites (all under one MM account) and have to email MM support, then wait on a response, anytime I want something changed.
As far as multi-site membership system goes, I would love the option to see features where one MM plugin can talk to another MM plugin installed on a separate URL with certain permissions that are established on the backend admin panel.
Thank you for your input! Even though MemberMouse will not be implementing this suggestion, your feature request provides valuable insight into the needs of our community and helps shape future plugin decisions.
