Google Analytics custom variables usage?

That is a violation of Google Analytics terms of service . See number 7 PRIVACY.

No. While it might be possible to accomplish this with Google Analytics, it's mainly meant to be a statistical tool so you're better off tracking the users on your own server or using some other service.

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.
