I'm really new too, but I really liked the aporoach, posted (or blogged) by someone here, of determining your OWN personal BMR by tracking how stable your weight is at different calorie intakes and activity levels. The BMR formulas are just estimates so this observation/tracking experiment would take some of the guesswork out of how your specific body works. (Hopefully a more experienced member will jump in with a link!).
Other suggestions I found useful were either to weigh yourself regularly and adjust your eating/exercise to stay in your range, or to use a pair of goal jeans and make sure you're in the good fitting zone.
Congratulations on reaching maintenance!!!
