I have 4 sites: A main landing area, and 3 separate sites for kids in a school system - elementary, middle and high school. I want a user to be able to register for one site but not be able to see the other sites' content. But a year from now, some of the kids from elementary will need to move to middle school. As of right now, even if I put the student in the middle school site manually, they get an error message (Site Access Denied). Plus, this page redirects so no one can register anyway. http://highlineschools.net/middle/register
I was in the live chat ... no resolution. Also I had to uninstall the WPMU dashboard because of issues with getting stuck on the network privacy settings page.
