You can now create your threads in your Back Alley, then when they are to your liking, move it to another forum.

How:

If you create a thread in the Back Alley, at the top you will see a --> Streets --> OOC --> DT BD and so on.  Clicking this will move the thread to the forum you select.

Sample Use cases:

You are working on a really important thread with lots of formatting, you want to get it perfect first.  Boom, looks good, click to move it to it's final destination.

You are setting up a open RP that is pretty intense, there are 4 people that create the set up for it, but its important that all 4 get their posts in the proper order before it goes "live".
