I cant play ps3 online every time I click sign in it says playstation network is going under maintenance?

That is true psn is under maintenance, if your logged into psn before the maintenance starts you can still play online, and due to the maintenance has already started you cant log in.

Don't log out of online or that will happen.

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.
