What do you think of a "Mentor" badge being awarded to a user who has helped the same poster numerous times? I.e. If a poster asks 10 questions and I answered all of these questions and received the accepted answer for each question I would be awarded the following badge:
"Mentor" being a gold badge for 25+ accepted answers for the same poster.
"Buddy" being a silver badge for 10+ accepted answers for the same poster.
