Some time ago, we introduced "just in time" tag warnings on Stack Overflow.
These warnings are meant to provide users with just-in-time information to help them avoid common mistakes in the tag they're using (e.g. SQL questions should mention the engine they use).
Here's what they look like:
Why Am I Telling You This?
If the Ask Ubuntu community feels this might be useful, then we could experiment with tag warnings here. This is pretty easy to configure on our end (Stack Exchange) if you can provide us with tags and associated warnings (those can include links and basic HTML formatting).
However, note that this feature is still experimental, so we don't know how well it performs, if at all (and we might eventually remove it).
If you think Ask Ubuntu should experiment with this feature, please provide a tag and corresponding warning as an answer (consider including an explanation, too!). Upvote suggestions you agree with, downvote suggestions you disagree with.
Of course, more general comments are welcome too!
