Need some clarifications on Event+

Hi i’m testing event + and i need some clarifications.

First, i have created a group as supadmin, so i seted up my paypal credentials and added a paid event to my group.

A member of my site, a normal user not supadmin, created his group and when he want to add an event, he can choose a group that he’s not the admin, and not member. In my example he can add an event to my group…

And about paypal, it’s only working for the supadmin ? Because users have not options to set up their paypal account.
