To get a ticker like mine, click on it, and it will take you to a website.
Scroll down to the bottom and just off centre to the left you'll see something that says Personalise your Space. Directly under that is the option to choose a ticker. Click on that and it will take you to some tickers.
Choose the ticker you want and enter the relevant information.
Click on Generate Ticker Info (in a pink box)
You'll get various codes, you need to copy the one called Pseudo HTML, UBBCODE, OR BBCODE.
Then go to your signature, which can be found by going to the User CP button at the top of this form. Select Edit your signature from the left hand side and then paste the code into that.
You should have a ticker!
