Love this plugin, it's helping me create a really nice community network. One problem I'm having though, is that if I make one of my users a Super Admin on their sub-network, they can then go into users and see / edit / delete users for the entire global network. This is obviously not a good situation!! Is there any way I can stop sub-network Super Admins from doing this? I need sub-network Super Admins only to allow them to create new sites on their sub-netowkr.
