It's free no hidden charges nothing. Once the month is over... Well it's over haha.
Yes you can cancel anytime you want. In your account, it will tell you the exact date they will start your first charge. Just be aware that after you sign up, they will put $8 on hold (not charge) in your bank/credit card account to make sure your card is legit.
Once it clears within a few days, they will release it back. It says so in the fine print. I see that question asked on here a few times.
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.
