Hotmail likes to tack little MSN plugs onto the bottom of all its outgoing messages; there is no way to stop the unceasing thrust of their self-promotion from reaching your correspondents. While they are diligent about their shilling, their proofreading leaves something to be desired. Apparently MSN users get access to new, more expressive emoticon-smiley things now, but that is only a guess; my most recent e-mail from a Hotmail-using friend just commanded me to “Use Custom Emotions! Try MSN Messenger 6!”
