MSN Messenger API Help

Hey,

I've been working with the MSN Messenger API for some time now and have a very lovely little chat bot created. He recognize multiple users, and user levels and all sorts of stuff.

The problem is, I want to get him to send files and I don't know how. I know most of what I'd probably need to do, but I can't figure out what to put in for 'ICookie'.

If someone could pass this info along to me, either by a reply on here, or in private (so that virus writers can't hunt it out), that'd be great.

Thanks!:)
