It feels a bit weird to see lemm.ee users posting as if their accounts aren’t going to be dead in less than a month.
Edit: Sorry to lemm.ee users if this is how you found out, but this is real: https://lemm.ee/post/65824884
You’ll need to join another instance to keep posting: https://join-lemmy.org/instances
You have until June 30th, 2025, so you have 19 days.
Partially, at least not what I use regularly. The account settings has a system for exporting settings, communities and block lists. You cant really retroactively move comments and posts to have been made by another user, but making a post on both the old and new users claiming eachother should propagate to other instances and be archived correctly.
