We've been working on a little something with Bart Decrem (npub1eej…kpl5) and friends and it's launching today!
https://sub.club/ is now online and already integrated into IceCubesApp (npub1cnh…wtw0)
It's now possible to subscribe to premium feeds right within the app, and you can create your own premium feed and content at https://sub.club/. It's simple, and the flow will integrate nicely with Mastodon!
