I got our room parents to collect money through Venmo. I hated sending in cash (and one time it got lost), and checks were often not cashed for months on end, which drove me batty. A couple years ago I decided to send my contribution via venmo, and I told that particular room parent that that was how I would be paying from now on. Within a week, all of the classes at my school were collecting money electronically, either through Venmo or Cash app. It's SO MUCH EASIER to keep track of, for everyone involved. I'm such a trendsetter! :)
