The address is here.
https://www.paypal.com/
Once a person signs up and adds their credit card or bank account they can then send funds online to her email address which, is the same as her paypal account.
Just click on send money, and type in her email addy and a few other things. She then gets an email telling her money has been sent to her account. At this time she can trasfer it to her checking account and it would be spendable in about 3 working days. Its really easy I use it for ebay all the time.
I know some might not have a paypal account and might prefer to send a check. But im not sure she would want her home address posted online.
If any freeper could make it a clickable link that would be great, im not up on that yet.
