Hide Content from logged-in users

Hi Developers,

i really like the Plugin so far, its exactly what i was looking for 🙂

now my Question: I know you can hide Stuff from users with the [restricted] tags. But can you hide Things from every logged-in Person but show it to not-logged-in Users?

Background: i want to put the register/login stuff in my downloads-page above the (for non-logged-in users hidden) Downloads and hide it when someone logs in.

edit: I took a different and better approach and dont have the problem any longer. Out of curiosity i would still like to know if its possible though 🙂 Maybe by using a level thats reserved for not-logged-in users?
