Line up clarification

I've already submitted a line up for this week. In fact, I submitted it before the extension through to Friday happened. I am disinclined to submit another line-up.

If I now make trades, what does my line up for Friday have to be based on? What my roster was Sunday night, or what my roster will be Thursday night? What about everyone who has not yet submitted a roster?

Uh, I'll talk in more detail with the GMs whose trades I am pursuing, but it occurs to me that timing might matter to me.

Richard.
