Hi Atlantis! Welcome and we're glad you found us.
My experiences have been a lot like Mel's, though I ate more while I was losing. I started out at 1600 calories/day and ended up at about 1200/day. I also exercised a lot (hour of cardio/day, weights 5X/week).
When I reached goal, I added in about 200 calories/day and my weight pretty much settled into where it is now (I didn't alter my exercise routine or anything else that I was doing). My body shape and body fat % continued to change, however, due to lifting weights and building muscle, though the scale stayed the same. I'd say my maintenance level currently is 1500-1600 calories/day -- as long as it's clean food. Any sugar-y cheats make my weight go sky high!
I've done the BodyGem test twice: the first time it said that my RMR was 1485 and the second was 1600. Based on these numbers, I should theoretically be able to eat well over 2000 calories/day and maintain, but it doesn't work that way in real life.

So my BodyGem experience is almost identical to Mel's -- interesting info, but not very useful.
In my opinion, as long as you're accurately tracking your calories, you've got some room to play around with the numbers and see how your body responds. But like Mel says, take it s-l-o-w-l-y. Any sudden big influx of calories is going to show up on the scales!
