ivyhill, Is the above response supposed to be a stab at humour ? What is your problem ? I asked a very reasonable question, in a very reasonable manner that is totally undeserving of of your sarcastic, unhelpful reply. Since joining this forum, I have contributed often, insulted or belittled no other forum member and generally observed all rules to the best of my ability. To receive such a glib reply from somebody who goes by the grandiloquent epithet of "Global Moderator", quite frankly dismays me.
