If I can add my twopenny worth, I have lost track of the number of times that I have become exasperated when I click a button on a website only to get a message asking me if I am sure that is what I want to do. OF COURSE IT IS OR I WOULD NOT HAVE CLICKED THE BUTTON IN THE FIRST PLACE. Happily this site is free from such shennanigans, the less clicks to reach one's destination the better, plain background essential, the fewer top frame distractions the better (most of us don't read them anyway). Message you are replying to one response page? Just possibly althoug up to now I have been able to remember the points I wish to respond to. Years ago a character in a TV series had a catch phrase "I have a plan of the utmost simplicity" let that be our motto. I'll shut up now.
