More than a month ago, we've reached a consensus: We want MathJax back. The reasons why it was turned off in 2015 no longer seem to apply, and details about why MathJax is needed on this site are detailed in the linked post. After a while, I asked a Community Manager about what we shall do next, but they were probably busy with other things (such as the election that was just about to start), so I didn't get my question answered.
So, what should we do to have MathJax re-enabled? Can we please have it back?
