Well You'll have to read through the terms of service of the company providing you access to allow CC activity. If it is google check there terms of service it should spell out how much they will charge you on CC transactions. PayPal also allows you to accept credit card payments and spell out how much they take.
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.
