permissions in home directory

[Francisco X DeJesus]

    Ok, here's the situation: I'm trying to set up a guest account with
a fixed .login and .cshrc. I thought of simply putting those two files the
way I want them set up in the guest account's home directory, and have them
owned by root, group root, and read-only (permission: -r--r--r--). The
problem is that even with this setup the guest can delete them! What did
I miss?
