ADMIN MESSAGE: I'm posting this on this specific thread as it is of especial relevance to some posts here, but please take it as relevant on all posts. I'm not trying to be "on the case" of anyone here - this just triggered what has needed saying for a while. 1. PLEASE trim prior material when responding and do not include large amounts of prior material. The norm is to include enough to allow the context of your response to be understood. 2. Equally, please do not respond with NO prior context shown unless the material is relevant in its own right with the given subject line or if the material and what it relates to cannot be misunderstood. Trivial example - if several people have posted on a subject then responding "Very funny" is not able to be understood without looking back at prior posts, or at all.
