If I decide to migrate, you will all be imported to follow that account, but in the meantime, during this "trying out" period, you'll have to refollow the sakurajima.social account.
Also, to populate my home timeline over there, I will follow everyone I follow here from that account as well. I don't have that many people on Follows (which I should fix by finding more, to be honest), so it shouldn't take that long. I'll just put some music on in the background while I do so.
But yeah, just know that if you receive a follow from there (or a follow request, if you have that turned on), it is me.
