Differentiate Income

[David2000]

I have Paypal Donation buttons at two websites, kojiroskorner.net and art-3000.com

I would like to be able to differentiate them so I　know which Paypal donations are coming from which site.

Is there a way to do this?  If not, the solution obviously is to have two different Paypal accounts, but is

this possible?  Thank you.

Create two differnet buttons, each with its own Donation ID.
