Your page links do not pass term1 term2 etc. back to the server. Also if you are going to pass them in the link then you need to check $_REQUEST'term1' $_REQUEST'term2' etc. to cover both GET and POST requests.
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.
