BK is using the Ghost blog plugin currently. They have a recent content widget on the home page pulling only blog posts, but for some reason it is pulling in yet to be published blogs created using the ghost blog feature. Are these supposed to show up in widgets? Since they are not published yet I would assume not, and test with the default publish at a later date feature does not pull these items in.
That widget shows blogs based on the currently logged in users permission. Any user who has the permission to see the draft group would see this in their recent blogs widget, but a regular user wouldn't.
