Note for D6 users: Sorry, you have to do this in other ways.
What you intend
It is assumed that you have the node types "news", "event", "group", "group_event".
Organic Groups is installed. "Group" is configured as group type, "Group event" is configured as "group content" type.
Richard III of England found dead.
Celebrate the new king.
Royal dinner club
Discuss new home decorations.
How you do it
Configure like this:
Parent path for nodes of type "News".
Parent path for nodes of type "Event".
Parent path for nodes of type "Group".
Parent path for nodes of type "Group event".
Probably it already works.
Otherwise, go to
cut + paste it up into the "Enabled" section, and move it as far up as you need to, to make it work.
