It seems to me that problems in infinitary combinatorics (a significant area in set theory) should naturally be tagged "[combinatorics](https://math.stackexchange.com/questions/tagged/combinatorics "show questions tagged 'combinatorics'")". Some users disagree and remove the tag from such questions. 

Should the description of the tag "combinatorics" be expanded so the inclusion of these questions is clear, should a new "infinitary combinatorics" tag be created, or do you see a better alternative?
