Jim has been very clear on all that.
The more relevant question is why the majority of users give zero, zip, nada $$. If the users were doing the right thing in decent numbers, first, there would never be a FReepathon; and secondly, the owner would be doing quite well w/o catering to advertisers.
I donate every Freep-a-Thon but my name never shows up. It used to but not anymore. I use the PayPal feature. They had my old e-mail address and I changed it this time to my curerent one AFTER I donated so maybe that was it. Or am I supposed to put my nick in the comment box?
