Hey, your thread was closed so I'm responding here. If you have a request that a mod can do, such as moving or closing a thread, you can report your own post (there's an ! icon for reporting) and a popup you can write in will appear.
Also, it's possible to close your own threads in most cases with the drop-down toolbar at the top of your post. Thread Tools -> Close Thread. If you need a thread closed and can't do it yourself, use the report function.
