How to toggle view?

How do I make it so that people who are not logged in see one message and people who are logged in, see another? I created an HTML component named "newbies" with permissions for "other" set to "view" and permissions for "mygroup" not set. then I referenced it in a link +newbies+ I still see it even as a member of "mygroup" . On the otehr hand, I added a component named "grouponly" and set permission to view for members of "mygroup" and no permission for "other"... If you login as a member of mygroup, you can see it, but you can't see it if you're not logged in. What am I doing wrong? Thanks, Lawson
