I thought client submit to every relay. That’s how Iris and Damus work. If you only submit to one, your posts are only visible on one
Damn, that sucks they did that! >:(
OK, I've added all those relays now, thanks for the advice!
I'm using the command line tool nostr-tool but when I submit to multiple relays none of the posts ever show up, only when I submit to one relay alone, so I though given that relay.damus.io appears to be the most used relay at the moment it would make sense to submit to that one.
Do you think I should submit to a different relay?
I hope one day I'll figure out how to submit to multiple relays simultaneously, I've left a note in the git forum for that CLI app at https://github.com/nbd-wtf/nostr-tools/issues/152

The client submits to all relays that you have configured on your account to submit to ("write"). For example I have configured the relay.damus.io to be read and write and all others to read only because I don't want people to think I'm submitting to more relays than the damus one. I wish I could submit to more relays than one simultaneously on my CLI tool but at the moment it doesn't seem to let me do that, it only allows one at a time which is different from your experience on most web client and apps where you can select "write" access for all your relays if you want to.
OK, I've figured out how to do it, so now our app is submitting to all the relays at once!! :D
