You can use Pacifist to install just Terminal.app from your original install disks, or if you send me a private message vai the board i'll just stick the .app online somewhere for you.
You sent me an email via the board but there was no return address. I just sent you a Private Message. To read it, log in to macosx.com and look near the top of the page. It should say "(1) Notifications", I think next to "My Account". Click that and you should get the private message.
