This question already has an answer here:
I see that the Identification tag is very popular on GL. My opinion is that retagging with the identified species could help users to avoid posting duplicate questions. For example, if someone wants to identify a rose cultivar, when writing the question a suggestion for already identified roses could appear on the Similar questions list.
However, this retagging would need new tags to be created. The problem is that for some species there would be only one or two identifications, and this rarely used tag would clutter the tag list.
Do you have any idea on how to mark these resolved identification questions with their species name, without overcrowding the site?
EDIT: Or maybe a tag for the genus, not for the species?
