New community federation issue: https://fedia.io/m/santafe

Folks in sopuli.xyz are not seeing posts to /m/santafe. It was suggested I go to https://lemmy-federate.com/ to submit m/[email protected] for federation. But I would need to be an admin on fedia.io to do that, it seems. Instead I am a clueless noob, trying to learn, as we all create the fediverse. Suggestions and assistance would be much appreciated!!
