I finally figured out how to create a blog signature! On My Live Signature, you can choose from dozens of fonts, sizes, and colors to create a snazzy signature to add to your blog or email! Just follow the directions to convert to HTML, and copy the HTML code. Sign into your blog on Blogger, click on Settings, then Formatting. Go to the bottom of the page, and paste the code into the Post Template box. Then Save. That's it. Every time you start a new post, the signature will already be there.
