It's maybe a little bit early to ask that question, but it can occur, that questions are asked, which are off-topic, and a tag is created therefore. Example: How could Aang stay alive for 100 years? avatar.
As discussed in the question, avatar is not topic of AaM, hence the question is closed. But what should happen to these tags? If I see the tag, I think "Hey, there's a tag for it, so I can ask!". Should be anything done about wrong/off-topic tags?
