This question already has an answer here:
I came across this question, which is fairly old, has 2 very good answers (with a good amount of up-votes), and the OP has stated in his question that both of the answers are acceptable. Yet they have not accepted either and simply left a note in their original question about the "correct" answer.
Is there anything that needs to be looked at here? Should I comment that the OP should accept an answer if they have one? Should I flag it?
