To answer your question, once you create a new thread, you can not delete it. Use the triangle Report Post icon at the bottom left of every post to report it to a moderator and ask for removal or to move it. You can delete a post in a thread within an hour, but you can't delete a new thread.
Do not post the same topic in more than one area. If you want it moved to somewhere else, just use the Report Post icon and ask a moderator to move it.
I hope this helps.
