I am pretty new to silverstripe and want to use it for a school site. Therefor I need the possibility to have some "editors" (students) who are able to edit the content of the pages and save, but not publish it. Then a "master editor" (a teacher who is not the administrator) needs to review and publish the page. In the help pages about permission codes (http://doc.silverstripe.com/doku.php?id=permissions:codes\) I found that with "Can edit any page on the site - Ability to edit (but not approve or publish) any page across all sites to which you have access." for the editor role and "Is a CMS workflow admin - Can do anything within workflow (approve, publish etc.) Basically a global override of all workflow." for the master-editor role but I can not find this permission settings in the demo installation or my newly installed test system. There are also other permission settings missing in my testsys which are mentioned in the doku, I see 10 codes out of 21 on the help page.
How can I add these missing permission settings?
Thanks in advance
