Facebook Chat API - Is Chat possible with 2 unknown users?

No, the only way to do this would be through the use of the Send Dialog where you could specify the UID of the non-friend in the &to parameter. There is no API method publicly available for sending messages to non-friends.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
