Well, as a new member, let me clue you in. It is difficult, at first, to search the forums. The trick is to select Search, and then select show posts and this will de-select, show threads, which is very confusing, then enter your research topic. We have had many, many, many lively discussions that include those that support it and those that don't, and all those in-between. Frankly, I can't think of another subject on DT that has been discussed more and discussions usually end.....abruptly, ergo Burns' very wise advice. Have fun looking around and welcome to DT :wavey:
