In XE, how can I set what can certain group members do. For example, I have just created a group called "Editors". What should I do to let these group of users to have "create/update/delete page" rights?
As far as I know (using the Page module) you can only give to a certain group of users the permission to modify a page, but not to create a new one or to delete an existing one.
But the Wiki and Board XE modules have the option to set the permission you wanted.
