I am trying to creat a multisite whereby new users can automatically register and get a new site - but only one site. I've successfully installed 3.1.1 and the registration works except that new site admins have the ability to add more sites. I was hoping that I could solve this with your plug-in. However, after installed, each site now lists ALL networks sites under their respective My Sites regardless of which default in your program I set. This seems like it should be any easy configuration - but I have not yet found the solution.
