Ron, (as it is my middle name I think it is OK to call you that?) you have my complete sympathy as this is the problem with forums and that is why there are emoticons which may help to convey the sense behind the possible riposte; but they do not always work and so you have to rely on past experience as to whether you think the poster has a sense of humour as they can develop into full blown war. I have been in a number of them.
Please don't stop posting!....................you rat-bag.
