gpg: WARNING: Using untrusted key!

Hi,

I'm getting a peculiar warning message when I verify signed messages;
even messages signed using my own keys (GnuPG v1.4.1). Here's a sample
verification of one of my own messages:

gpg: armor header: Hash: RIPEMD160
gpg: original file name=''
gpg: Signature made 03/16/05 18:58:05 using RSA key ID 973073CF
gpg: Good signature from "Melissa Reese <snipped at calarts.edu>"
gpg: WARNING: Using untrusted key!
gpg: textmode signature, digest algorithm RIPEMD160

I know that my key is given "Ultimate Trust", so I'm a bit confused
about that, but I get this same warning when I verify anyone else's
signed messages as well:

gpg: WARNING: Using untrusted key!

Does anyone know what this means?

Oh, by the way, this is on a WinXP SP2 system, with GnuPG v1.4.1

Thanks!
