Well, I've submitted my script after the current window opened on Friday (21st). It might seem a little keen to send it so quickly after opening, but I'm away for the rest of October so I had little choice, other than to wait for the next.
I sent the pilot script along with a series outline with episode descriptions. They ask for 1-3 pages, but even after trimming yet keeping it readable, my outline ran to 4 1/2 pages. Hope they don't mind.
Anybody else sending material for this window?
