i wonder if there is any way that a moderator approve all the content posted by members before it become visible on site is there any way to do that or any plugin ?
ThankYou.
You would need a plugin or customization. I also want this for my own site.
But i can't find any plugin for that probably i must go with customization
https://www.socialengine.com/marketplace/app/moderator-toolbox check with Webhive as they have a moderator plugin that maybe they could add or customize for your feature.
I can assist with such customization. My team can do this for you. Contact me if you are interested.
