My computer is only running Windows 7 RC. Will I be able to upgrade to the final version or will I have to buy the full OS?

If you don't own XP or vista, you will have to buy the full version. Otherwise, everyone would download the RC and then get the upgrade price.

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.
