Yep, I agree with Maurice that the game would stagnate if no input. It's difficult to say what the time limit should be, given that (eg.) USA is just getting into its stride when it's close to my bedtime, and WbB is up like a lark, fresh as a daisy, full of the joys, etc, etc, (OK, I'm being facetious - I'm sure we can sort something out)
One thing that hasn't really been decided is a common dictionary. I, personally, am against using ONELOOK, as it's full of . as (I think) some of the words in it aren't acceptable. But, hey, it's a democracy.
PS. I don't know how to set up a vote.
