The tag alias #57796 demon_wings -> membranous_wings has been approved.

Reason: I was going to make this an implication request, but then I realized that "demon wings" just means membranous wings that happen to belong to a demon, and what does and doesn't count as that is subjective. Also there aren't a lot of posts tagged with it at this point anyway, maybe for that reason.

EDIT: The tag alias demon_wings -> membranous_wings (forum #338189) has been approved by @bitWolfy.
