Welcome to the Q&A Forum

Actually the Rank Tracker Tool will be going away in it's current form.  We are working on coming out with a new version of that tool and you can leave any feedback or feature requests you have here: http://www.seomoz.org/blog/what-does-your-ideal-rank-tracker-look-like-we-want-to-know All that info will be sent to our product team who will decide on the new features.
