HTML in signatures

[Guest_imported]

Hi, does anyone know of a way to insert HTML into signatures in the outgoing mail of Outlook? I just need to insert a simple HREF, so I can give a reference to a URL without having to have the full address shown as part of the email. It's a simple matter to do within the email itself, but I cannot see a way to insert it automatically
at the bottom of the text.

TIA, pat.
