I am trying to create pages that are viewable without a login, but if a person does login I want certian pages to display customized content. For example, I have a calendar page that loads up to anyone. But on the same page I want to restrict showing the hyperlink to "Adding a calendar Event" to someone who logs in with that permission. How can I do this because the login examples i have found through form based authentication require that the whole page is either shown or not show. Is this correct or am I wrong?

Thanks in advance.
