The tag alias #75554 rin_wolf -> reinawoof is pending approval.
Reason: ei-ka (the owner of the character tagged as "rin_wolf") would like the tag to be changed to "reinawoof". The "rin_wolf" tag has existed for a while, but as ei-ka doesn't have an E621 account, they were unaware that their art was being reuploaded here with misleading tags. They're fine with the art being posted, to the best of my knowledge, but requested that the tag be updated to more accurately reflect the character's actual name and species. I offered to update the tag/submit an alias request on their behalf, they said that would be great, and suggested "reinawoof" as the new tag.
So yeah, here we are.
I'm pretty sure this is the right place to submit this kind of request, but if not then that's my bad.
