Log out text link only

[busymum]

I have taken out the nav bar in the header because I didn't want any log in or log out button or create account etc. However, now I think I need to have the log out button show up once someone is logged in (and only if they are logged in). I tried copying and pasting the original code for this but it does not work. Does anyone know the code I can put in the main page so that the log out text link shows up (and works) once someone logs in. Thank you.

Nevermind, I've worked it out. I just couldn't see the text because it's white!
