Allow each event organizer to enter a Pay Pal address other than Group Organizer's Pay Pal Address
When you click Pay Pal as the payment method, there should be a place to enter the Pay Pal address you want to use. This will allow Assistant Orgnaizer to collect money before "Yes" R.S.V.P's can post. Currently it defaults to the Group Organizer's address. Each event organizer needs to be in control of the money for the event they post.
Consider moving your votes to this suggestion:
Each time we have an event, the Event Organizer buys the supplies (foods) and it is a hassle for me to collect the money and redistribute it (plus Paypal gets double fees) I would like the ability to directly assign the money to the person who needs it to buy the supplies.
