This is probably a duplicate...
Question 1
I'm often asked to review edits made by users with even less reputation than I. Many of these edits texify titles. But on this page it's written
Ensure that the title contains some actual words, and not only $\LaTeX$ -- the search functionality of MSE does not interact well with typeset mathematics, making questions comprising only $\LaTeX$ (much) harder to find. Furthermore, the MathJax context menu (which pops up when you right-click on some typeset expression) overrides the browser's link context menu, making e.g. opening the question in a new tab difficult.
I this policy still in force?
Question 2
It seems to me MSE policy is to start the title of a question, as often as possible, with an upper case letter. Is it so? (I, personally, tend to start with an upper case letter when the title of the question is a sentence, ending with a period of a question mark, and to use lower case letters otherwise, but I don't mind changing!)
Question 3
Where are users supposed to find answers to such questions?
