I had thought I read somewhere that we can set a plugin to allow users to message one another only if they have paid for an upgraded membership. Now I can't find it here, so I am wondering if there is a combination of wpmudev plugin that can make this happen.
Basically I am thinking of using the membership plugin with something like supporter and messaging?
Is there a way to make is a user can not send messages through the messaging system unless they have paid? I'd like it to be free for users to read messages sent to them, and have them have to pay either per message sent through the system, or pay for 24 hours access to send messages maybe.
Not sure if this should be a different set of plugins to achieve this.. any help is appreciated.
