Today, completely out of the blue, I got a box from Vonage. Inside was a Vonage cap, a Vonage T-Shirt, and a real honest-to-goodness "thank you" note from Vonage, thanking me for being one of their "best referrers." I don't think I've done that good of a job, but evidently they do.
Of course, if you're reading this, and you want a free month of Vonage... email me. :)
