Hi. I would like to ask if its possible to change an existing artist name to the latest one.
Currently, the site tags is Koafune . I tried to look for a way to change/edit this to (Acetyl_Koa) but was unsuccessful.

The pen name was change recently and to prevent any confusion when looking for the tag, I want the name to be same as other SNS (pixiv, twitter)

create alias koafune -> acetyl_koa

You should prefer aliases so users can still find the artist. You also should not manually move or rename artist tags, nor should you remove URLs (just prefix them with "-" to mark them as dead). For future requests, please keep it in topic #7713.
