Hi - I thought this is basic CMS requirements - so maybe I'm missing something.

I need to create a group (say Editors) that can only Create/Add/Update pages - not publish.
Only the administrator has the right to publish to the live site.

How is this accomplished ?

Based on an earlier post to the forum, I tried to add the canPublish function to the Page_controller class without success :
protected $publisherGroups = array(
"Administrators"
);

function canPublish() {
$member = Member::currentUser();
return $member->inGroups($this->publisherGroups);
}

Thanks - impressed with SilverStripe so far.
I'm comparing with TypoLight and BigMedium.

Hi there, sorry for the late answer. We've done a bit of work lately to better enforce the SiteTree->can*() permissions in the CMS-Controllers, which is going to be released with 2.3 soon. Sam is also working on a basic workflow module, you can check its progress here: http://open.silverstripe.com/browser/modules/cmsworkflow/trunk

As a sidenote, we usually check against permission codes rather than groups directly. So your canPublish() logic could also be implemented like so:

function canPublish($member = null) {
   return Permission::checkMember($member, 'ADMIN');
}

With the PermissionProvider interface, you can add your own permission codes for a more flexible management.
