Any ideas?

I wish I could magicly get people to sign up for Inboxdollars! I get emails everyday right in my Inboxdollars Inbox and with the toolbar I see that there is new email as soon as I open Internet Explorer. It is really easy and user friendly, especially compared to the other sites i've done. I have made $18.00 so far which is not that much but if I could get some referrals it would work twice as good. Plus they would be making money too, so I dont really understand why I don't have any. Hopefully this will change soon... I'm open to suggestions people. I think it's a good money maker, thats all i'm sayin.
