Small Delphi application - MSN Messenger Connect

I require a small application that can connect to MSN Live Messenger, retrieve all contacts, and then send a message of my choosing to each contact. I am looking at the MSN protocol here: [login to view URL]:Authentication Now I am using a TClientSocket, and just using 'SendText' to send each command, and so far it connects fine and works. However, I can not work out the 'Tweener' authentication section. It needs to send a long authentication string from 'Tweener' but i'm not sure where this string is obtained from. Please use TClientSocket for this project, and hopefully you can solve the tweener issue, and then move on to retrieving the usernames, and sending the message. This site managers it: [login to view URL] ..and also here: [login to view URL] This code can be used i'm sure. Kind regards. ## Deliverables Program with area for a message to be sent, an area for username and password, and a send button.
