Do not refuse to send a post by telling me "This item has not been sent because it has already been sent" when I have made major changes to the original post (which was sent incomplete, by mistake) and wish to send it - which is the reason for this service, after all. Are you not here to do what we - as users - need, not to be acting like a disciplinarian schoolmistress, wrapping us over the knuckles for a minor infraction of acceptable behaviour - but failing to do something we need to do ? And my rewritten post has not been saved in Drafts, so now I have to remember what I had said (if I had known that it would not be saved I would have recorded it in long-hand). This is not the normally good service I have come to expect from Yahoo! - having now used the Desktop service for about twenty years.
