Networking sites doesn't appear to work. In my case I don't need to migrate existing sites, just create three linked sites (without WordPress integration). I created the three sites using the same DB. Each site has its own admin. I added the networking plugin to one of the "child" sites and added the two sites details to the "master" site. Posted question on the child site. No indication is showing that the two are linked. Many thinks on leads ... the install instructions on Git are not sufficient for my skill level.
