Question

I sniffed a bit when sent a message to a friend and found that there is a simple post message sent that contains a “tid” parameter .By this parameter Facebook knows whom to send the message.

So far I didn’t find any relevance of this parameter to user id or other aliases.

Does anyone knows how can I get this “tid” parameter from user who is not my friend ?
(because if he is a friend I can just fetch it from a source code when opening a message dialog page).
