Can we include a prominent link to MathJax in the Tour, a suggested here, and on the sidebar (bulletin) that displays on the right side when one is going to ask a question, as suggested in the comments by Martin Sleziak?
See also here and here for related discussions, where all points out that a showy link would be more than helpful for new users. Or perhaps, instead of the MathJax tutorial link, a How can I format Mathematics here link?
When one is going to ask a question, there are various links: the Provide details, the choose a good title, etc. I think the MathJax link explicitly is missing.
There's also this observation, when one is going to ask a question, this displays on the right sidebar.
Where there are 3 repeated links on both bulletins, the last 3 in the first bulletin and the 3 in the second bulletin.
Edit 2 I've also thought about this previously, and made a comment about it here. Thanks to Martin Sleziak's notitification, reminded me about that.
