For example - the names of the 101 clans of yadavas.
Yes I agree, I think there should be a tag for such questions. I have found many questions here which are utterly useless from religious point of view. E.g, how many names are there for Karna, What was the name of a particular chariot, what was the name of conch shells of pandavas or kauravs etc. Like for philosophical questions a separate tag
philosophy is maintained then why not to maintain a tag for such highly insignificant questions?
