Paranoia sets in

Ok, I've read Good Guy's from start to finish now and although it did come out with some red pen on it, I haven't dropped any scenes of felt the need to add any. I am going to go through it tonight and write how each scene moves the story along. If nothing can be written then I'll drop it.

Now, about the paranoia thing:

Not that I've sat on my script with a shotgun or anything like that, but now I have a complete script I was thinking of registering it. There are two places I have looked in to: 1) The WCA - UK and of course 2) the good old WGA.

Should I bother registering with both?
