There was someone else who said this in a similar thread, but I'm starting to agree. A really good way of doing MS is not in discovering new methods but in finding old ones that everyone else thinks has died and then making them work for you.
For instance, I had had a feeling that even though Serve was going to go to Amex only cards, there was a chance that if you already had a non-Amex card loaded, you could continue to use it after the sixteenth. Lo and behold, that turned out to be the case. Now the real question is if it'll last until next month.
