So I am looking for a way to create a group from the user id . The desired result is that when the user registers they are the admin of their own automatically created group. I'me lost as to if this should be done in site_events.php or userinfo.php, and have no idea what it would take to build this functionality. Can someone please point me in the right direction?

I thought this thread might help, but I wasn't able to make anything from here work to this end:http://www.concrete5.org/community/forums/customizing_c5/how-to-add...
