spaw,    i don't know if you are as intellegent as you try to make out you are, but have you thought that some of us haven't had access to a computer before now and it's a new experience for us to be able to join in.   though i do enjoy the verbal ping pong. and about allergies i hadn't thought of that even though i am allergic to cats. we had three before trying to live in a camper van (don't ask it was a disaster) i was always having colds but loved them loads so i understand how hard it is to do the right thing.
