how do I sync my fit bit to mfp

Go to http://www.myfitnesspal.com/apps/show/30 and link your accounts.

Be aware that the sync has been iffy since Christmas.

MFP has a a Fitbit Users group: http://www.myfitnesspal.com/forums/show/1307-fitbit-users

on your computer go to the apps tab, select fitbit (make sure you get the right one, there is also a fitbit scale in there), there will be a green box you can click the connect the acounts, put in your fitbit info and wala

hope you enjoy your fitbit, loveeee mine!
