Mustafa, I am aware, of course, that all of us AnswerBankers are sitting at distant typewriters, but I tend to think of the contributors to a thread as if we were a conversational group discussing the matter raised by the questioner.
In such circumstances, in actuality, anyone who simply said exactly what someone else had just said would be loooked at askance by everyone else present as if he/she were deaf or somewhat mannerless.
Accordingly, I myself always read the responses...and that clearly includes links...already on a page before contributing. Seems only polite, but maybe that's just because I'm am oldster!
