Question: How do I register my PayPal?

This question was resolved by phone, but I am replying for others who may have the same question:

Login to eBookIt.com, and click on the small "person" icon, toward the right on the navigation bar (it's to the left of the social media icons). The system will prompt you to login again (to re-authenticate), and from there, you can update your client profile. Update the field for "PayPal E-mail Address", and then scroll down and save changes. Moving forward, that will be the email address that we sent payment to.
