I would rather use custom CSS than creating second copy od website which will in the end mean, that you will have to maintain two identical sites (content wise).
If you are talkign about database, then you can of course have one common, but what are you going to do, when you decide to rename sole site field?(for example) – Dampe Apr 17 '11 at 13:17.
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.
