I was just writing a question on StackOverflow about regular expressions, and a big popup came up while I was typing.
Unlike tag alerts, which we've discussed, it didn't depend on me choosing a tag, and it was huge, with lots of detailed steps for me to try.
It looks like exactly what we want for font ID and critique questions.
What is it?
Can we have one?
