I have created a forum on my site, but would like to have an option where only the moderators can respond to the initial thread. I don't want to allow all the members to be able to comment on the initial post (this is for a coaching website, so I only want the moderator-coaches) to give feedback in the forum. I went to the tab for settings/permission, but I don't see an option for this. I want everyone to be able to POST, but only moderators respond. Thank you!
