don't install this!

the plugin works as advertised but it also puts all the users into hidden groups which can no longer be seen in the admin panel for any of the blogs in your network. this means no user tweaking. the only work around to make the user visible again is to grant the user Super-Admin privileges, but then after tweaking the user and setting the role back to something normal like Author, the user is hidden from the UI once again. the plugin author has no page for the plugin and his website has no links. i’m sure he meant well, but if i’d paid closer attention to those two things, i’d red flagged this and not installed it at all. stay away until the dev can provide a fix for this nasty bug. (and by fix, i mean one that doesn’t require me to go into the office and open up the myphpadmin and manually edit the database!)
