Since the thumbsdown button was removed there have its been a couple of occasions where I'd have loved to have it back - but only a couple - and on those occasions the need can always be met by posting 'Oh for a thumbsdown button!' in reply. On the whole I think this board is a friendlier place without it, so on balance it's a no thanks from me.
So in essence your thumbs downing the thumbs down? Isn't that like pooh pooing a pooh pooh? Who knows where that might lead...
