Hi
Math-SE is (obviously) not the only math-discussion forum out there. A poster that wishes to maximize the speed at which his question is answered may well choose to post the same question on more than one site.
Suppose the first and/or best answer is posted on a site other than Math-Se. What is the proper way to quote/link to it, without undue abuse of the reputation system?
Disclosure: I am new to this (and other) forums, and have committed this "sin" on my very first question.
