Congratulations on your launch, this familiar tipping model warms my heart as a musician who occasionally busks in NYC subways. I'd love to see a "Music" category as well as support for recurring donations. You advertise that it's free, but do Stripe and Paypal's fees get added on on the buyer's side or the receiver's side? Seems unclear. (During checkout is a $5 donation billed as $5 + whatever percent to the donor?)
