Request money online for a group trip

You're in charge of planning that trip you and a group of friends take every year.  Last year was great, but you saw how hard it was for Jennifer  to get everyone's share of the ticket payment and hotel reservations. And you heard about it a lot, too, because she called you up all the time to complain about it. Now you're concerned you'll be wasting a lot of time better spent on other things, like planning the week.
