If the Ticker was made on CafeMom:
My Homepage -> Manage My Tickers (this is in the Tickers Box on your homepage) -> Find the Ticker you want in your signature and click "Use It" -> "Save" as your Signature Name
If the Ticker was made on a separate website:
Personal Details -> Signatures -> "Add a Rich Text Signature" -> and post the link for the ticker in your text box. For me I had to save it and then go edit and save it again but that might just be my computer, it should just show up for you.
Hope that helps!!
