[ViewLevel] visibility without custom fields

[Thomas N. Burg]

Hi,

I imported lots of posts via RSS, changed the viewlevel to "0" but  
still all the old posts are visible and if I post a new one it is  
still visible. I tried to add a viewlevel manually via custom fields  
- this one worked.

Is there an easy way to add the viewlevel "0" to all imported posts  
and new ones automatically.

Thanks for any help

Thomas
