Same as Pennine, more so when someone who should know makes an incorrect posting and then gets stupid instead of saying "Whoops", but it doesn't signal the end for me yet.

sees that some people do nothing but ask questions and don't acknowledge the help given. They're lucky they get any responses but I can think of one that rarely does now.

I made just such a comment last week. I think knowledgeable folk who have taken the trouble to research will be less responsive as time goes by.
