@hzrd149 It seems like the new(er) version of Nostrudel requires that you set up outbox relays before you can post. Can it show an warning message or something if you don't have them set up or try to post without having them set up?
I don't use Nostr too much and it took me awhile to figure out why it was trying to post to 0 relays.
