Believe me, I get it. I wouldn't be crazy about putting my name and address into some guys website that I met on a message board where everyone uses user names. If you want to put Joe Smith from Alabama, do it, just make sure the email works cause You may need to contact me if you have a problem or a question, and you may win money in a free contest and I will need to know where to send the money.
If you're out there and you are leery about the registration part of it, then make one up if you want, as long as it's a working email it's ok. All I want is your opinion on sports. Nothing else. Not Money, not your home address, social, credit card information. You make an account so the tracker knows who you are and where to sort you depending on the filter chosen by the user.
