Idea: if you mod a community on a lemmy.somewhere you should be able to migrate it to lemmy.elsewhere which would include all post & comment links being forwarded and subbed users having their subscription updated to reflect the new location.
I’m aware this would be a way down the road as user account migration alone is still not great but it would be a great feature for the fediverse to have to avoid centralisation and mod/server admin wars.
when a user on a server is in a room it is “hosting” the room so if the server the room was made on goes down, everyone who’s not on that server can still talk in the room, that does make the hardware requirements higher compared to XMPP for sure which is a downside but I do feel like the positives outweigh the negatives personally at least
