While something that irritates is...well...irritating, we must always be careful not to 'throw the baby out with the bath water'. In my mind it's a case of 'expect the unexpected' and I must say that my own research over the years has been helped on a few occasions by various people making 'off the cuff' comments that have actually generated lateral thinking and real progress. Those fall into the 'hindsight' and 'why didn't I think of that' categories. As I said in a previous post (which seems to have been approved by quite a few people judging by the number of 'likes'), this is a brilliant Forum and long may it continue. If anyone doesn't like what one sees, then there are the options to ignore, note, make comment or, as I'm now about to do, 'clear off for a cup of char'.
