As some of you have noticed we've added the possibility of connecting a Stripe account to a Liberapay account. This is only a first step in our migration away from Mangopay, we know that Stripe only supports a limited number of countries, we're working on adding other payment processors as well, including PayPal which covers more than 200 countries.
The new page to manage your payment accounts is https://liberapay.com/about/me/payment/ (please excuse its shortcomings, it's a work in progress).
