I need to try that again if they ever fix my login. Before, when they gave 500 FD miles for signing up for promotional mails, I signed up, got the points, and a few weeks later got another email imploring me to sign up. So I did, got another 500 points, and of course the cycle continued. For a while there I was getting either 6 or 8 copies of all the promotional mails each time they went out.
