When one right-clicks on the subject line of a posting one has not seen, one can choose "Open link in new tab" or "Open link in new window" or "Bookmark this link" or any of several other options, unless the subject consists only of $\TeX$, in which case it says "Show math as..." and one can choose "MathML code" or "TeX commands".
