<p>You don't necessarily need a community wiki unless you expect others to edit it; just a single canonical version of the question with a good answer would suffice. </p>

<p>Surely there are some good candidates already present as answers. </p>

<p>If none are sufficiently generic, one could be chosen and edited to be made more generic -- or if substantial changes would be needed, a new one written and posted. </p>

<p>In that instance, whoever does the work to make a new one can get points for it as long as they properly credit anything they use. This is the model the network operates on. </p>

<p>[If you <em>want</em> to make it CW, you can, but I don't see it as required.]</p>
