Why is wrangling not okay as a tag? I'm curious.
I'm not sure I understood your question, but "tag wrangling" refers to the process of organizing tags. Users create new tags and misspell tags all the time, but you still want people who click on these tags to be directed to other works featuring tags that mean essentially the same thing. For example, you can tag your fic as "alternate universe" or "AU", and they will both lead to the same place. All new tags are looked over by volunteers who decide if they need to be merged with an existing tag.
