Recently, on new Code Review questions, I've been seeing this:
Welcome to Code Review! As we all want to make our code more efficient or improve it in one way or another, try to write a title that summarizes what your code does, not what you want to get out of a review. For examples of good titles, check out Best of Code Review 2014 - Best Question Title Category You may also want to read How to get the best value out of Code Review - Asking Questions.
I've seen this exact message multiple times, so I figure there is a meta somewhere, where you can copy this message.
However, I do not think that it is a idea to reference to the "Best of Code Review 2014 Best Question Title" meta.
By showing this to the new user, they could get in the habit of posting titles that, while they are interesting, they do not always tell a lot about the code or the post itself.
I think it would be better to just leave a note saying that the user's post's title should only be the function/purpose of their code. Then, as that user is more active on the site, they will begin to notice these posts with "special titles" and they might start to follow them.
It would be better for users to follow these titles later and write normal titles first because they learn good practices on this site earlier, and will be less likely to be poorly influenced by these "special titles" later.
