If your husband already has a facebook account with that email address, you cannot create your facebook account using the same email address. As their help center page says "you can only sign up for one facebook account per email address" If you attempt to sign up using the same address you will get the message that there is already an existing account associated with that address. There are many free email accounts to be had on the internet.
I am afraid you will have to take the plunge and sign up for one. :).
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.
