Quick question, how should I go about cleaning up and merging two artist tags that are simply seperate aliases the same single person has used? Retag all posts and transfer details from one artist to the other?

@404_ArtNotFound: make sure that they do not have two seperate aliases for good reason (e.g. sfw/nsfw) and then request alias that other name is aliased to current/more used one, all posts with other name is then automatically changed.
