Can you tell us Jeffrey, how one can delete a duplicate Post? Highlighting the Post and clicking on “delete”, doesn’t do it!
It has to be done within a certain time frame which is just a matter of minutes. There would be a small red X under the post indicating it can be deleted. Clicking that will take you to the delete screen. If the X isn’t visible then the poster has to bring it to the attention of a mod who then can delete it.
