Login/Registeration

Hello people,

I want to add this feature to my website where I have installed color mag, I want to show login/registration link or Usernam: Passwords: | Sign Up link on the top of header where people can notice of if possible a side bar maybe. So once the person logs in he shouldn’t see it.

Can I have some help on this ?

The page I need help with: [log in to see the link]
