Hi, Hutching
To PM the URL as AW Admin mentioned, go to your post in the thread where it now sits. Right click on the post number on the right in the post header (for instance, your post is #1 in this thread). You'll see a list pop-up, click on "Copy Link Address". When you PM AW Admin, paste that link address in your PM.
If it's a thread you want moved, open the thread you started and highlight and copy the URL address in the address bar at the top of the page. Paste that link in your PM.

P.S. You can also PM the room mod where the post or thread currently sits, and they can move it for you, too.
