Outlook Macro: how to specify a mail signature

[SteveBoard]

I'm working on a macro in Outlook 2003. I've got it replying to an email message with subject, body text, and attachment. I can't get the syntax right for adding a "signature" to the message.

This doesn't work: Item.Signature = "My Normal Signature"
Even though Item.Body = "text of message here" works

Suggestions?
