Wait until you start going to internet cafes on foreign trips, just to check the Mileage Run category to make sure you're not missing out on a bargain somewhere (or have your laptop along on domestic trips for the same reason). Addictive? Yes. Rewarding? Without a doubt.

Hope you're able to meet some of the FT'ers at an event, or airport, near you. There are some wonderful people on this board always willing to help others out.
