This question is similar to another one, so feel free to mark it if it is too similar.
Here's the story:
I'm on Seasoned Advice, and I see yet another question about how long food can be left out of the fridge. This time, however, the person asking the question says something specific about transporting their food, so I think to myself that this is enough to possibly make the question unique.
Naturally, as a new user eager to earn more privileges, I type up an answer, linking to a similar question about food safety, answering the initial question, and suggesting that an insulated container with an ice pack be employed.
Meanwhile, the post is marked as a duplicate of the one I was mentioning in my answer, and a commenter pretty much covers everything else I had said. I notice this as soon as I post my answer. Feeling sheepish, I promptly delete it.
Should I undelete it?
On one hand, most responses to the question (and its many duplicates) I mentioned at the top of this post seem to point to yes. On the other hand, I get the impression that there is some subtle etiquette involved here that I have yet to learn and am not likely to find in an FAQ, and I feel a little silly posting an answer that restates information already present on the page. And there is the possibility that I was answering a duplicate question, anyway.
I would also like to point out that I posted this on the Stack Exchange Meta because it seems relevant to any SE site. Correct me if I am wrong.
