If you want the normal user to add content, then you need to set the permission. Under People > Permission you will find node. And there you have to add the permission so that users can add content.
But yes, giving permission to users who add content directly has a lot of security implications.
If you have successfully created the content type then the link will come automatically under node/add link. But I am not sure if you mean the top black toolbar or somewhere else.
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.
