First of all, great plugin for multisite WP. My request / question regards post / page publishing right.
I have set 2 types of users : contributor who prepare post and author who can review and published them. Contributor is able to edit a published post, but all modifications should be reviewed by a authors before being published. Right now once a post his published, contributor modification are published too (unless he reset the post status to draft or pending review).
Here are screenshot of the setting for contributor:
Any idea to turn this around?
