Hi all,
I’m building a buddypress website to manage a science didactic project. I have near-by 20 courses and 20 students for each course. Is there a way to add users in bulk to a group.
I have found a plugin to add user to a site in bulk – http://wordpress.org/extend/plugins/add-multiple-users/ – but I don’t ho to add users in buld to a buddypress group.

Thank you,

Andrea
