In Communities there are currently two types of group settings for posts - Read only, which restricts posts and comments except for admins, and Standard, which allows posts and replies from anyone on the channel.

I'm requesting two more settings options

1) Read Only, but allow replies to post - so users can discuss announcements but can't do unique posts of their own.

2) Post Approval Required - where any user can post or reply, but it must be approved by an admin before becoming publicly visible.

It seems that expanding the permission options in the above ways would greatly enhance the usability of Communities/Kollab.
