Hi Marty, I think there is a trick you can try. Edit the post again and confirm the edit to create a "new" post. You then get about 10 minutes in which a delete x button is available for the "new" post.
Click the delete button and the "new'' post will be deleted. Let me know how you get on.

On Wednesday evening I made a post and didn't see the delete option a little while later. I think it may be the same as what I've seen on other forums, i.e., you can't delete after another post after it is made. Things can get confusing if you delete it and subsequent posts quoted or responded to it.
