At the moment, if a member meets the page restrictions to view a page, they also have the ability to interact with the page if it's interactable (e.g., comment on forum posts, create classified listings, post recipes, etc.). Instead, have two separate levels of page restrictions. One would be view-only, allowing people to view the page without having the ability to interact with the page. The other would be view+interact, which would be the same as it is now.
Add Restrictions similar to other pages on who can post to Classifieds. Our HOA posts classifieds on behalf of vendors, so it would be great if homeowners couldn't post to it if we only allowed admins to do so.
