Compose dialog
Click New Post on Posts to open the compose dialog. You stay on the Posts page while editing—there is no separate full-screen editor route.
Title and body
Enter a title and the post body in the dialog. The body must meet the minimum length shown in the dialog before you can publish or schedule. Use the character counter to see how much you have written.
Optional image
You can attach one image to a post when supported in the dialog. The preview on your profile may show a compact “+1 Image” hint when an image is attached.
Profile preview
Use Preview on profile (when available) to see how the post will look on your public page before you publish.
