For those interested, I've added material to the Zeev's Ideas Board (#board-1351).
Zeev, I switched from "underline" to "bold" for your comments for the reason I mentioned earlier. All those who responded, other than yourself, preferred that I use "bold" to highlight your comments.
If there are others, like Zeev and myself, whose browsers do not display "bold", please offer a suggestion for resolving the issue.
