Hi there!
For the bar that shows you the weight loss, I clicked on someone elses and it takes you straight to the Ticker Factory website, follow the steps for the weight loss one, desgin your own ticker , (it will be password protected too) and then copy the first URL to paste it in to your signature -at the beginning, it will just be a website with lots of number, but when you preview it, you will have the ticker that you designed show up.
HTH and that I didn't confuse you!!
