proby untill i get 5 usefull posts in here. have to explain a bit.broke my shoulder,titanium in,retired myself so as not to cause an accident to a colleague,went to studying autocad,a never ending process.also doing benevolent work for handicapped ----all this to say i do not own my free time.feeling myself around this site so that i may one day contribute, but for now lurk and glean the wisdom of others silently, till i kick in. i have some catching up to do ,so much material to digest. ok, i know i have too many things on my plate, but that's the curse of a 65 year old man who feels hes got just so much time left to get things right. i think i found a home.
