Where does the money go ? what do I have to do in order to recive the money ?  maybe link paypal acoound somewhere? 

Is it via Email? if it's via email how do I change the email ? 

That's right, payments are sent via PayPal. If you go to you dashboard, there's a Payouts tab. Enter your PayPal ID at the bottom. You might have to tick the "Developing and uploading games" checkbox under "Account type — How will you use your account" in your profile settings for it to appear.

ok thank you I found it and I've seen I linked the right one
