Interesting idea, but I am not sure whether there would be easy way to make a distinction between the two.
Perhaps elementary-topology would contain, roughly said, the stuff from topology which is often mentioned in the courses in analysis, usually in the context of Euclidean spaces or metric spaces?
@Martin Since general-topology is one of the most frequently used tags, it would be good to discuss this at meta first, so that we hear opinion of more MSE users.

@MartinSleziak I was thinking that roughly the first five chapters of Munkres would be "elementary", that is, things covered in a typical one-semester introductory topology course: continuity, separation axioms, compactness, connectedness and basic countability axioms (first and second countability, Lindelöf, separability), Urysohn and Tietze's theorems. Notions such as paracompactness, nets and filters and metrization theorems would probably be borderline.

@Martin The questions what to do with the question already tagged as general-topology will probably come up. It would be a lot of work to go through 5k questions and check, which of them should be retagged. (And this only can be done by few questions at once, so that the front page is not overfilled by the questions bumped in this process.)
The largest retagging I have seen here was the removal of algebra tag - there are several discussions about this on meta. When I joined the effort, the tag had about 700 questions and it still took quite a long time.
