What it says:
Players can vote and discuss who should be acting first officer and that choice is announced by the captain as if she chose it.
There are five of you active right now but if there should be a tie I'll cast the deciding vote (most likely will flip a 2 sided die).
You get 1 vote, can change your vote while the poll is running, and the poll runs for 4 days (sorry need to have a decision in advance of the next turn).
