How great is this latest Bot, from the MSR-MT team Windows Live Messenger translation bot now available!
Really easy to use and setup in a few seconds on Windows Live Messenger, and on your smartphone.
To get started just add firstname.lastname@example.org to your contacts, then start a conversation with TBOT ? to get a list of commands, and then for example enter 7 (for English to Italian translation), then type your message and you get a machine translated response such as
‘quanto freddo è il Bot in tensione di traduzione del messaggero delle finestre’
Update – just also added this to my Office Communicator and of course it works fine there too.
