I just started using this so I know very little.

From what I gather, there’s a default channel called “LongFast” which every device has from the start. I can see some messages in “LongFast” where I am.

I can see I can create another channel and share it via link, QR, etc.

Do people make such channels and share them publicly, for say local or topical chat groups? E.g. “Canada”, or “Meshtastic Support”, “BurningTesla”, or “Cats”? Is this a thing? Can it be a things?

When I check local groups info, I see links to online comms like Telegram (ew), Discord, Matrix, etc. I don’t see Meshtastic channel links.
