4702: Missing permission options (default permissions too extensive)


What version are you running?


What's the URL of the page this enhancement relates to, if any?


Describe the enhancement and the motivation for it.

Extend available permissions (both user and role based). I would really appreciate to have an opportunity to make some users not being able to post reviews and approvals and modify reviewers/review groups after first publish. I would also like to forbid submitter/owner to post approval to his own review request.

What operating system are you using? What browser?
