The tag "artist:dandychamp" doesn't exist on this site, so ... that's already gone. Maybe it disappeared during the migration to Philomena.
Deleting your existing artist list is kind of a problem, since the artist badge shows that you are an artist with a publicly visible artist link. If I delete the link, then your artist tag is "unverified" and you are no longer an artist ...
o you want your artist tag changed to match your current profile name (artist:slimyferret)?
And, would you be ok with your artist tag being "just your art here on this site?":/tags/artist-colon-teapyramid If so, I can do that.
