Yes, and I have no problem with it's existence. If you post a stupid question, and that makes you realise just how dumb you have been, then deleting it before anyone notices or answers is fine by me. But, when it is a complicated answer that can take half an hour to get right, and the OP deletes it as soon as he reads it, that does annoy me, I admit. If nothing else, it doesn't appear in any list I can access to copy it or refer anyone else to next time...
Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together. Manfred R. Bihy: "Looks as if OP is learning resistant."
