SSRS 2008 is fully compatible with SSRS 2005 reports. From my understanding upgrading is a one way trip however. Once it's been upgraded it will no longer run in a 2005 instance.
So, keep a backup copy handy if for some reason you need to go back.
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.
