how do I add two tickers to my signature?

not sure what you mean by two tickers....

huh?

From Cake Central's Terms of Service:

<<FORUM SIGNATURE

You may post a link to your website in your signature, as long as it does not link to any inappropriate material. You may also have a "counter" or other signature image linked from another website as long as they are within the following guidelines:

1. Images must be no more than 100px high or 600px wide
(give or take a few pixels)
2. Only 1 Banner image, or Counter may be used in your signature
3. Absolutely no obscene, violent, or adult themed images are permitted.>>

So, maybe you can only have one ticker (i.e., an image with "2 days until I get married" or "20 pounds to go!", right?) in your signature.
