Some more info would be helpful. What page is it? Does it say it is managed by someone else or is it showing not managed at all?
As for editing, it's super easy. On the page, there will be a page builder on the top left side. Use this to add sections and such.
Above each individual section, you will find tools to help you move, edit, etc.
If you claimed the page, it should show up under your account. The fastest way to check is to click on your username in the upper right hand corner of the screen. It will then bring you to your account where you can see pages managed.
If it's not there then you may have not claimed it correctly.
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.
