Just a heads up that if you are using MNET, and also want to use the new user policies system in "privacy and policies", then you need to ensure that the "policy agreed" field is not being passed between the two Moodle sites in your MNET peer connection. We were getting browser errors saying that there were too many redirects. See https://tracker.moodle.org/browse/CONTRIB-7756
This took a day or two for us to spot, but now seems obvious!
