• [fun] will be used for humorous, light-hearted, seasonal or celebratory activities/posts/etc.
• [mix-up] tags items that might have been the subject of confusion or misunderstanding; it seems this designation is not yet set in stone.

(Caveat lector! My guesses, so I hope they’re not too far off the mark. 😉)

it’s now possible to search by tag, and find the questions with these two tags.

What are these two tags for?

I’m guessing we might want to keep fun and maybe rename mix-up to by-design or something like that?
