What is the correct procedure for removing tags which only have a single question, and would be better off with a less specific tag?
My example is a question which was tagged 'relative-entropy'. Since 'relative-entropy' was too specific and only had that one question, I retagged the question with 'entropy'. Was this the correct course of action? Or should I have used a tag synonym instead?
By the way, how does one go about deleting the tag 'relative-entropy' which is now vacant?
