Trackers?

Where/how do you add the weight tracker that people have on their profile? Ya know, the thing that is on the bottom of people's replies that shows start weight and goal weight, etc.

It's complicated. :)  

Go to "View profile" (top right of this screen under your screen name), then "customize profile" which is on the left side under your screen name.    There are several tabs in the middle of the screen:  General, Profile...HEALTH TRACKER.  Click Health Tracker.  On the next screen, there's a blue radio button that says "Go To Health Tracker."  Click that. Then click on "Tickers and Widgets."  The weight trackers you see are Tickers.  You can create them there. 

Good luck!
