Pax vobis, everyone. This is very much an instant site where Q & As are posted rapidly. Sometimes we might give offence when none is intended. For instance, when I answer a Q which has been asked earlier, I will also post "answered before". My intention is to avoid claiming credit for the diligence, knowledge and intellect of another AB. However, this may be construed by a questioner as a criticism that he or she did not check previous answers before. That is not meant.
Let's just rejoice in the goodwill that permeates the site, and forgive the occasional blip.
WB :-)
