When you update your ticker and then you click on the updated ticker in your signature it will open the page with the graph and weight ticker on it. (This is how I do it)
Just under the graph it says add Your Graph to your Blog, web page, post...if you click on add it will open a page with codes and you need the BB code for here.
You copy the BB code then edit your signature here on MiniMins and paste the BB code into your signature box and click save.
Every time you update your ticker and graph on the Tickerfactory website it will automatically update here.
