<p>Some clarification about how SE works:</p>
<ul>
<li><p>Editing a question doesn't automatically re-open it; it populates the review queue where reviewers will vote to reopen it or not. Not everyone who participates in the review queues understands the details of every question in the queue, so it can take time for enough votes to reopen a quesiton.</p>
</li>
<li><p>A new question can't be closed as a duplicate of a question with 0 answers. (Except by a moderator; this exception is rarely utilized. It is generally only used for the case of a user repeatedly posting the same question over and over again.)</p>
</li>
</ul>
<p>My advice is to wait a day. If the question isn't reopened in the next 24 hours, you can post your question &amp; answer. If you like, you could even post a comment on the closed question linking to your question and answer.</p>
