This question already has an answer here:
If an answer is accepted and a later answer is a better fit and/or more accurate is the only recourse to let the voting resolve it assuming the OP of the question ever checks back on their already assumedly answered question? Or in the case of the linked instance where nitsua60 posted a bounty in what appears to be an attempt to sway the changing of the answer, in this case the original was correct until Crawford recanted and clarified.
Is there a way to draw the eye to help encourage "re-voting" with this new information?
First ever question so please let me know if you need clarification to help with your answer(s).
