Our new Guidelines for Inadequately Referenced Answers include some suggestions:
Welcome to Skeptics! Please provide some references to support your claims.
Could you please provide a reference for your claim that the tallest ever person was 2.72m?
I can't find in that source any evidence to directly support your claim that the tallest ever person was 2.72m. Could you please quote the relevant section or find another reference?
I prefer to customise my answers, but I do use the first one as a template with the AutoReviewComments userscript as a basis, or when I am being
lazy efficient. It adds the "Welcome to Skeptics!" prelude only if the user is new (by some arbitrary rule).
