Thanks for the answer.
Everything works.
Issue resolved.
Notepad++ is my favorite text editor.

Special thanks to you for the clarification about the publication of posts and for additional information on the topic of the question.

As the GUI clearly indicated before you could type your post, as a new user, when you make a post, it goes into a post queue, and will wait there until a moderator has time to read and approve the post:

What option in the settings do I need to turn on or off so that I get this result?
