@cyclar2 There's an option over here for that, It's right above the posting box, just the word preview with a down arrow. Maybe it needs to be enabled by an admin?
@viv@cyclar2 This is kind of an annoying workaround, but on clients with a "Delete and redraft" button (like Enafore) you can do a test post with "Direct" visibility so nobody sees it, then change that post as needed!
