what bad stuff specifically would happen if i changed my username, other than @ links breaking (i can handle that)
everythign is id based internally so not much.
just old links to /users/theawesome98 will 404 (and old mentions in posts and comments wont update). you can fix it by registering the username youself and telling people to go to the renmed profile.
if anything does break, thats a bug on my end so you should let me know.
and of course you can always change your name back.
you can also do https://beta.wasteof.money/$id and replace id with your user id. Since the id can’t change, this link won’t break. (it works for prod too)
