How you would base a new signature on an existing one: On the Tools menu, click Options, click the Mail Format tab, click the Signature button, and then click New.
Type a name for the new signature.
Select the option to use an existing signature as a template.
Choose the signature on which you'll base the new one.
However fancy you want a signature to look, it will probably contain the same information as a plain signature. That means you don't have to create a new fancy signature from scratch. You can use an existing signature as a starting point. What's more, if you like the look of some else's signature, you can ask them to send you their signature file so that you can copy the look.
In this case, we're using the Bobby Moore (Plain) signature as the starting point.
