I finally got around to signing up for it only about a month and a half ago or so. Because of that, it's going to take me a while, but I'll get there. I certainly appreciate this method much more than just the Adsense or Amazon alone as I'm seeing better results with this already.
And to the person who wrote about losing the PayPal account: I've had a PayPal account for years and have never paid for it. The only time I'm aware of you needing to pay for it in some way is if you have a business. If you use just a personal account, I don't know why you would pay.
