I guess you sign them over top of the numbers on the reverse...although it does little good as you then can't read either the signatures OR the numbers.

Glad I'm not alone. By mistake I signed over the magnetic strip. The magnetic strip is silver in color, as compared to my other cards which have a black strip. The card has been working fine so far. As the previous post mentions, I also thought the color on the front left hand side looked silver but has the text "GOLD" over it. Do not forget to use you card 15 times before 11/15/03 to get an extra 100 miles each time. Not a large sum but 1,500 miles for free is 1,500 miles for free!
