You've made some good points, and I do see what you mean; it can be quite discouraging to be told that a particular subject has already been dealt with; still, if it has, it's fairly pointless (and self-indulgent) to repeat comments that other people have already made.  Further discussion is welcome -and frequently valuable, as it can provide new insights- provided that contributors take the trouble to find out what has already been said.  Most of us, as newcomers, have failed to do this from time to time; it's quite difficult to sort out the technicalities of searching the Forum, for one thing!  In the end, though, people who want to join a club -or use its facilities as guests- do have to understand that there will be generally accepted procedures that we either go along with, if we want to make the best of it, or don't, if we can't be bothered.  Learning curve stuff, really.
