Those later round will it just select my picks for me or what? I have work so I might not be able to finsih the draft.
It's anticipated that all GMs will participate through the end of the draft, including the "press conference" threads and voting.
You have a co-GM, right? I'd try seeing if he can make some of the picks you'll miss. (If not, just send a list of players you want to another GM, and see if they'll pick for you.)
