judy,
How in the world do you have over 11,000 miles in the Milesbar account?? I joined as a platinum member, surf/on the computer all the time, and have amassed a whopping 272 miles according the the milesbar.
My account page has a 1,000 sign up bonus listed, as well as 200 for a referral. Beyond this -- zilch.
Maybe you have everyone else's miles that seem to not be accumulating!
