It is not. It might still be on the school's network, but I did it back in the spring and our department's network admin might have wiped my account since I graduated. Didn't accomplish too much to be honest, as might be hinted at by the frustration underlying my post.
You can certainly blame our (old) doc for that. Sorry for the bad experience -- we're definitely still at the stage where I wouldn't expect people to be playing with Urbit and not asking for handholding. Even more so this spring.
