What's the earliest I can pick?
Noon, when I announce the trades. Draft should be very laid-back.
How does submitting trades work? Both participants have to send them to you before noon tomorrow or what, in general?
I'll start accepting them at noon, trades work like this:
If Guy A and Guy B are trading, they both send me identical trades with their okay.
My team trades: Player X, pick Y
His team trades: Player A, pick B
I accept.
Guy B does the same, and as long as I don't veto it for gross incompetence, its a go.
