Just to help others who want to get one of these date & dollar sig pics:
Look around at peoples sigs and find the one you like. Hover over it and click. Some may not be clickable, choose another until one clicks
through to the site where they're available and follow the instructions there to fill and copy code. When you get back to ECF, click settings up at the top of the page. On the settings page, go to the Edit Signature page from the link in the left column and paste the code from the sig site into the sig text window. Voila!
You can has sig? Yay!
