I don't think you can edit a comment/status once it has been posted. I mean, if Facebook users can't edit their previously-posted status updates, why would Facebook allow apps to do so?
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.
