I've already found this older thread with the same quastion, but using Wordpress is not an option:
Does anybody knows a CMS or some other piece of software which allows a user to register and create/edit one single page? The user should only be able to manage it's own page, nothing else in the adminpanel should be visible.
Pages created by the users should be inactive until a moderator reviews and publish them in the normal site structure. Any suggustions?
At the moment I'm using couchcms but it has no ACL-feature at all.
Thanks in advance
