The epsilon-delta currently does not have a tag wiki.
Can someone propose one?
Below is why I ask the question
Motivation 1: every proof in hard analysis is, in some sense, an $\epsilon-\delta$ proof. So I don't really see the point of such a tag. If someone can point out a more restrictive usage of this term that would be nice.
Motivation 2: I've seen a lot of beginning students use the phrase "$\epsilon-\delta$" to refer to any rigorous proof, possibly because their first introduction to mathematical proofs arise in the context of a course that uses, for example, Baby Rudin as a textbook. If that is indeed the case this tag smells rather like a meta-tag to me.
