[Sigia-l] Designing a site with restricted content

[david natas]

Does anyone have any thoughts about the best design strategy for a content 
managed website where much of the content is restricted depending on the 
type of login a particular user has?

Should all restricted content be hidden until an appropriate login is used? 
Or should all items be visible to all users, but with a login page between 
selecting the link and viewing the actual content?

any thoughts or links to relevant information/research/case studies would be 
greatly appreciated.
