Log user into facebook using session key from my Facebook app?

No, the user must login on the mobile app as well. Using a mobile Facebook application is no different than using your Desktop application on another machine. The login must occur for security reasons.

If you could pass around pre-authenticated URLs this would be a major security issue as URLs are easy to steal. See mobile authentication .

So from what I've read - it looks like this functionality is available in a private API, but for normal people, it is as 'plafayette' says: not possible.

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.
