A post preview lets non-members see a post before they join. It's a way to show off your content and turn casual visitors into members. You set it per post with the Public Preview toggle when you create it.
With a preview on, non-members can see the post, but they still have to join to do anything with it, like comment or buy.
What non-members see by post type
Post type | What's visible | To do more, they must |
Text | Title, body, comments | Join to comment |
Image | Image, title, body, comments | Join to comment |
Video | Video thumbnail, title, body, comments | Join to comment |
Product | Product image, title, body, comments | Join to purchase |
Preview off vs. on — example
Public Preview on: the post is fully visible. Non-members still have to join to comment.
Public Preview off: the post is obscured. Non-members have to join to see it.
