I posted a question and someone answered. Then, another user
commented on that answer (with a different solution) and I ended
up using this second solution to solve my problem.  Should I
mark that answer as accepted (even though I didn't use (or
tested) the solution given in there)? And how do I give credit
to the user who commented and solved my problem?  share|improve

call them out -- to put their comment into an answer, so you can
upvote and accept it. Often people will do this if you ask.  As
Martijn Pieters points out, if they don't do it themselves after
a reasonable period of time has passed, you can create the
answer yourself, marking it as community wiki (so you cannot be
accused of reputation pilfering), then upvote and accept it.
