For anyone who is interested (and this may be something that everyone but me knows already, so bear w/me if I'm repeating):
When you get ready to adjust your ticker, you don't have to go through the process of creating a new one all over again. The last line of the hyper link has #/#, with the first # being the total pounds you want to lose (at least it is in my case) and the 2nd # being the total pounds you've lost so far. In your signature, just change the 2nd number to correspond with the pounds you lose as they change and save it. It'll update your signature without going through all of the steps.
