Crash I've forgotten the details about that software, but basically the idea was to use a card up to it's limit..... paying the payments from cash advances from another card etc etc but the $ limits he was talking about were way more than you are quoting, just as a matter of interest I have a business Amex with NO- LIMIT (I've never put em to the test, but there is no limit) and a platinum Mastercard with $80,000 limit, I didn't even ask for it, every few months they just send me a notice to say that my credit limit can be increased if I want it, scary.
