I typed in the text in the standard type face (Helvetica), style (Regular), and size (12 point):
With a blank message in front of you, type in your text. The first step in creating a fancy signature block in Mail is to launch the app and immediately click the New Message button. Follow along as I create this signature block. So what's the secret to doing this? Easy - use a blank new message as your canvas for creating the signature you want, and then copy and paste it into a new signature block in Mail preferences. It's nothing too fancy, but it provides links to the locations that are important to me and also to the social networking sites I use. I wanted to have three major components to the signature: my name in color so that it stood out, links to the websites that describe my work (TUAW being one of those sites), and the ever-popular links to my Facebook, Twitter, and LinkedIn pages.
So attractive, in fact, that I promptly stopped doing the writing I was working on and decided to create my own new signature to replace the ugly one I had been using.
I was leafing through some emails this afternoon and came upon one with an extremely attractive signature block.
