Cloak Text Upon Logon?

[redhawk89]

Is there a way to make a "join now" message dissapear once a user has logged in? I want the second line here to go away if a user has logged on, not sure what code to use...

edit: this is using straight-up text in the header, I kind of want to keep using jsut straight up text in the header. Just need to find out what code to put to make a line dissapear upon logon.
