Okay so basically the @prav project is meant to make it easy to get people onto federated messaging with #XMPP (which is kinda like #ActivityPub, but for private messaging). We use phone numbers to sign up, but unfortunately those phone numbers get exposed to anyone you talk to—so we want to optionally let people set a different username instead 🕵🏼
I managed to find a firm willing to do it, but for a fee...which you can help fund here: https://prav.app/donate/custom-username 💰
