I'm a happy lemm.ee user and a mod of a small community hosted there. I'm also subscribed to a bunch of communities on lemm.ee. Sadly, they have just announced that they will be shutting it down. I understand that I can open an account on another instance and subscribe to the same communities. For my own community, I can probably re-create it on my new instance and DM every subscriber. But how do I find all the communities from lemm.ee in their new places? I'd like some practical advice.
