Yeah, those free sites actually do work, but they require some time on your part to get anything out of them. They can be addicting, but it is easier if you have friends who are willing to help you out and get a few referrals. If you sit at your computer for hours checking them, then it would be easier to just work and buy what you want. But if you just use some type of advertising and let that find referrals for you, then it pretty much is hassle free. Conga lines are another pretty good way to get referrals and helps everyone involved to get more. I would recommend checking out the referral link thread at the top of this forum for advice about these types of sites.
