Re: Allowing group members to lock/unlock pages created by members of the group
As far as I know, only the page author can lock and unlock the page.
You can restrict read access by giving the group tiki_p_view permission for the page. This means only the group has read permission, and so denies permission to users not in the group. The permission can be assigned on an object level to the page itself, or by creating a category, assigning the page to the category, and giving the group the tiki_p_view_categorized permission for that category. See "Groups" and "Permissions" at http://doc.tikiwiki.org for more information.
In relatively recent versions, the Tiki version is indicated at the top of the admin general page (tiki-admin.php?page=general).
