What are your thoughts on adding a Guest (non-logged) User Group and
Viewing Access Level to the core? It would be used for displaying content
to non-logged-in users, but *not* to logged-in users.
For example, you could use it to display a "Login" menu item to non-logged
in users, and it would prevent the "Login" button from being displayed to
logged-in users (since they are already logged in).
I know you can do this by creating a custom group, however, it seems as
though it's been a highly request feature since Joomla 1.5 (at least) and
would be very useful as a core feature on new installs.
