I'm thinking of having a button to purchase dedicated relays, if someone is providing a service to quick and easily spin up personal relays, I would love to have that added.

Think I should link users to https://nostr.info/relays/ ?

The "Deprecated Warning" is mock-up, and won't be shown to first-time users. It's to help clean up kind 3 relay lists, which I don't want to override automatically. I'll get this implemented now.

The "Direct Message relays" will also be automatic for first-time users. It's a compromise I made in NIP-17 support.
