I got this to work!! I love it, Thank you, Saving Cents with Sence , who pointed me in the right direction. It is sooooo easy!!!

In case any other bloggers are interested in adding a signature, here's how you do it:Just go to Mylivesignature.com. It is FREE and simple:
1) Once you click on "proceed" to create a signature, you can use the creation wizard, draw on your screen with your mouse-pen, or scan in an image.

2) If you use the creation wizard, you enter your name (or whatever you want in the signature), then pick from different customization choices (style, size, color, slope)

3) Once your signature is perfect, you'll have options to animate it (not FREE), download it, or use it (pick this to get the html)Once you get the html code, it is easy to add it to your posts in Blogger (sorry, I don't have the info for wordpress or typepad):
Go to Settings, click on the Formatting tab, then scroll down to "Post Template" and enter the html. Your signature should be in every post now- you can check by going to the create a post tab.
