Wims, I tend to offer my so-called advices by way of demonstration. Some people may not buy 'em much, but I like the idea of showing what you mean by what you say. (people who use English as a second language may not process the meaning out of you easily) As the saying goes, "a picture is worth a thousand words." I really don't give a flying F I make "enemies" as a result, unless you give out something sensible for me to agree upon. I'm not here to prove people wrong and be argumentative. I do, from time to time, admit my mistakes. Again, you have your own opinion toward this matter, and I have mine. Thanks for your constructive comment.
