multisite not showing for users administrators of a site with [wpuf-edit-users]

Great plugin, really handy, clearly you’ve put a huge amount of work in.

It seems to be working ok for my multisite install but maybe the behaviour of administrators isn’t what i’d expect it to be.

So I add the shortcode [wpuf-edit-users] so that I can have administrators edit the users on a page (great!)

The behaviour is that it seems to show all the multisite users when the user logged in is a super admin (network admin). However, for a site administrator (not a multi-site network administrator) I get the message “You don’t have permission for this purpose” for the shortcode.

Maybe this shortcode isn’t meant to be catering for multisites so much?

Not a problem if not, just curious for now
