Microsoft Outlook 2003 - insert signature

My co-worker wants me to switch over to a MAC. Everyday, I spend a few minutes just trying to figure out why my PC (loaded with Microsoft) behave the way it does.

Outlook allows you to create many different signatures. But here's the problem -
If you turn on Word as your default email editor, the 'insert -> signature ->....' option disappears from the menu. It seems that MS Word does not integrate too well with Outlook. To get back that menu option go to: Tool -> Options -> Mail Format , and uncheck the checkbox for 'use MS word to edit email messages'.

Now when you create a new email, click on 'Insert -> Signature' , to add your signature while writing the email.
