[Mediawiki-l] Selective information displayed for logged user

[Gaetan Lord]

Hi,

Is there any way to display information in a wiki page only if a user
is logged in.

The long story.
On my main page, I'd like to have specific information displayed only
if the user is logged in. I wonder if there is any way to use some
"ParserFunctions" to check if we have a logged user or a guest.

{{ #if loggedUser .....

There is the isLoggedIn check that I could do from an extension, but I
would rather prefer to not rely on extension

Thank
