Every so often someone sends me a contract or something to sign and fax back to them. My days of owning a fax and having a second line for it are long gone. I end up printing the page, signing, scanning and emailing it back.
Here is a digital way to do it in Lion on your Mac.
1. open the pdf in preview 2. click on the annotate pencil 3. under S, create signature. write it on a piece of paper, hold up your sig to the window on your mac, line up on the blue line 4. accept 5. sig is stored 6. click and drag to where you need it on the pdf. resize if necessary 7. repeat process if you also need to date the form
