Ok...for all that follow...

If you move servers, I'm hearing you need to re-follow everyone. Those that dont move still keep those that did move as a friend / follower. If you move, you lose all your past toots.

Servers host accounts. New server may mean new emojis etc, but unlike twitter, Mastodon allows you to talk to anyone, on any server if you follow each other. So moving is really an aesthetic thing..
