Which Organizations Have Standardized on Mozilla?

andy brunetto asks: " We are investigating email clients to deploy as our "standard" at the college where I work. I'm trying to find out who is using Mozilla for their email. When I say "who" I mean organizationally, as I realize 99% of us geeks already use it. What organizations out there are rolling out Mozilla as their standard web and/or email client, and why? Yes, we are considering using Thunderbird, once it is final. Thanks!" Hopefully this will make companies realize that the Internet isn't comprised of just IE users.
