The history files skype uses are stored in ApplicationData\Skype\ (where is your Skype alias...if you can't find this folder be sure to have hidden folders viewable, and then search for a folder named "Skype") The history files have an extension of .dbb. You would have to copy the files from all the computers to some sort of removable media, and then copy all the files to each machine. I am assuming that these machines are not all networked together.
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.
