To clarify: this is in response to whether or not we want an "A" prefix? I assume they'll either all start with A or none, depending on winner votes?
Anyone can choose any of the four prefixes (well, except those that want shipping to the US, then L is out). I will settle the serial prefixe with everyone starting with the winner, who has already chosen. I'll send you a PM when I know the answers from the bidders above your bid.
