first of all, nice site. I'm only here because of the free ipod, but I browsed around a bit - looks like you're running a pretty tight ship. Hope it generates some revenue for you.
That said, I've noticed a few things related to the free ipod deal.
1) Your site does
own Google's pagerank. That's how I got here. Yours was the second link for a "free ipod" search.
2) You've already received your ipod. Are you letting others use your link? You brought up that possibility in one of your posts.
3) You're signed up for a free flatscreen. Assuming you still need referrals, I would be happy to complete one for you if I could borrow your ipod referral link. If that's not what you're looking for, I also have 30 gmail invitations. (But then again, who doesn't?
I appreciate your efficient solution to the problem of finding referrals, and hope that we can find something mutually beneficial that will score me an ipod.
