Does the weight loss tickers work on any sites and if not what sites do they and dont they work on?

The reason why I'm asking is because I would like to show my progress with a ticker each time I reach a goal but there isnt enough room on your Signature for each ticker so I was wondering if there was a site or blog or something where you can add a link to the site or blog so others can see your progress without having to a long signature? I know this site doesnt allow links in your signature but I'm asking because of other forums I use. Thanks for anyone who can answer my questions.
