apparently the answer is
If Word is your e-mail editor and you want to add a signature to only one message, you can manually insert it
In the e-mail message, on the Tools menu, click Options, and then click the General tab
Click E-mail Options, and then click the E-mail Signature tab
In the Type the title of your e-mail signature or choose from the list box, click the name of the e-mail signature you want to use. Under Create your e-mail signature, select the signature text you want to add to your e-mail message, and then press CTRL+C
Click Close, and then click Cancel
In the e-mail message, place your cursor where you want the signature to appear, and then press CTRL+V
This is VERY cumbersome. It was be much easier just to create a separate file and include text from the file
