When my customers are sent to the PayPal website for checkout they see the following text:

PayPal is the authorized payment processor for (my_email_address)@comcast.net.
I want it to say:
PayPal is the authorized payment processor for Tennessee Genealogy Books .com.
Like I see for other websites I have purchased from that use PayPal to accept payments.

I have looked at everything I can find on PayPals website but I can't find the information about how to make the change.

Can anyone point me in the right direction?

Thanks in advance!
