Quick Question

Go to /etc, copy the hosts file to your desktop. Modify it, and drag it back (you'll be asked to authenticate).

This also worked for me...however, why can't you just use the "Get Info" on the hosts file and give your account read and write access? I tried this and it didn't work. Is there a logical reason why not?
