When reviewing questions the blurb mentions:
These are the first questions a new user has ever asked on TeX - LaTeX.
When reviewing answers the blurb mentions:
These are the first answers a new user has ever submitted to TeX - LaTeX.
However, if I understand this correctly and as new user suggests, this excludes "experienced/inexperienced users on other Stack Exchange sites"*. I would consider "first questions/answers" on this site to denote exactly that - the first question posted by an individual on TeX.SX. Should this ambiguity be addressed?
