You would have to export all of your content out of your wordpress.com blog and move it to your own hosted provider. There are many providers that will host wordpress for you. Godaddy, HostGator, and others.
Once you have the host and install the wordpress.org blog system, you can import your content back in. Just be careful when setting up themes and try to have the settings as close to your original blog as well.
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.
