New tool to determine BMR and calorie goal

Nice new website that will determine your BMR and determine calories need to reach goal weight in determined time frame. What I like about this site is I set my activity level by what my work is like and how much I exercise. So it uses 2 factors to determine calorie burn and not just one. Plus I can play with the site to see what if scenarios, which i like alot. It appeals to the geek in me.
