<p>Ask what to do on Meta, linking to the question under discussion; it will attract attention &amp; more up-votes for your correct answer, making it clear to future readers that the accepted answer is flawed.</p>

But considering the case where an incorrect answer has been accepted with an up-vote or two, &amp; a correct answer has zero votes or a down-vote, would it be an appropriate use of Meta to ask for more eyes on the question?&mdash;after of course following @Nick's advice.]</p>
