[Zope-CMF] Non managers ca not access CMFForum

[Robert Rottermann]

Hi ther,
I added a CMFForum to a plone site.
I tried several security settings but non managers can not access the forum.

What settings does a user need to be able to access a CMFForum?

And I can not add a new forum trough the standard plone folder_contents/add
mechanism.
I have to create the forum on a vanilla plone, and copy it to the target
site.
What could be the reason for that `?

thanks for any hints

Robert
