The Ask a Question page shown to new users contains a lot of guidance, including a link to MathJax help:
Now, there are strong UI reasons why this link is nowhere near as useful as we'd hope, but we can at least make it point to something that's actually useful. It currently points to this tutorial, which looks like this
and which is nowhere near a useful resource. Despite the claims in a recent attempt to duplicate a bunch of work and create a local tutorial of limited usefulness, we do in fact have a long-standing go-to tutorial for MathJax, over on the Mathematics meta site,
The equivalent link over on Maths.SE links to their tutorial. Since we're already linking off-site for this, why don't we also link to theirs?
This has a fair amount of support. Is it something the mods can change? Do we need to contact the community team? Have already done so? If so, have said whether it's feasible or not?
