When you add a new profile to your watch list, I have found you need to do some editing in order to get the tracker thing to work. Once you click on "save", the various challenges show up. so you fill out the heading of what challenge you are working on, then it adds the new profile to your total. At least that is how I find it to work the best.
Once you create a new profile, then edit, they don't later count how many more edits you make on the tracker; just on your contributions list as normal. (I hope you understand what I am trying to say, cause I just added three doing it that way. lol) Sandra.
