I noticed that there were five recent questions tagged with rank, out of a total of seven question.
These five questions where all about rank in linear algebra.
Given the multitude of meanings of rank in mathematics, not all isomorphic, I decided to create the tag matrix-rank and removed all instances of rank.
No matter how useful the tag matrix rank is, it certainly is more so than the ambiguous tag rank.
I propose to ban the tag rank, whether the tag matrix rank sticks or not.
How does one actually go about making such a proposal?
