Well, didn't my previous post have substance? It's like everything I say nowadays gets buried. I'm going to guess it's power users trying to silence the small fry.
Your first post in this thread was empty. Unfortunately there is a kind of "pile on" effect, where all your posts in this thread get downvoted even if those posts don't deserve a downvote.
Hopefully that will correct after a few hours - other people will upvote any incorrectly downvoted comments.
