<p>What I would do:</p>

<ol>
<li>Accept the answer to your first question</li>
<li>Move your second question as a new question</li>
<li>Flag the answer to your second question asking to migrate the answer to your new question.</li>
</ol>

<p>I think this is the best course of action to keep the website organized. Additionally people get their reputation if they care.</p>
