I know that Amex and Diner's Club have specific programs for miles, whereas Visa and Mastercard depend on the bank that issues them. But why not a forum for them to let travelers know when there's a bonus promotion, new card offering, etc?

For example, I saw a deal for a new Platinum US Airways card from Nations Bank (soon to be Bank of America) that offers 1.2 miles for every dollar, double miles for US Airways ticket purchases and no limit on the number of miles you can earn annually. Don't know what the annual fee is, but I would think that this would be the kind of items that would be posted on a VISA Forum.

Anyone else think this might be a good idea?
