What are tag warnings?
Tag warnings are meant to provide users with just-in-time information to help them avoid mistakes that are common for the tag they’re using.
Here’s what they look like:
To see a tag warning in action, begin asking a question on Stack Overflow and tag it with sql. (More information on tag warnings can be obtained here, from which the above text and image were taken.)
This question
New users are often unaware of our requirements for questions asking for translations, meanings, differences and similar and thus ask questions that are not well received or could have received much better answers. By educating these users beforehand, we increase the chances that they ask good questions, get useful answers, and feel welcome.
So, I am asking: For which tags do we want tag warnings?
Each answer should contain one tag and a suggestion for the warning. If the same or a very similar tag warning makes sense for more than one tag, they can be featured in one answer.
I think a main target should be the problems covered by our custom close reasons, in particular recommending askers to say how general references did not help them.
This data-explorer query lists the tags that are likely to be used for questions that are closed. (As this excludes deleted questions, so the absolute numbers are comparably low.)
When suggesting a tag warning, try not to overwhelm the asker with instructions. You can link appropriate FAQs though (yes, links work in tag warnings).
