Wil: I abstain from this vote. It's yours and Sharon's game; it should be your decision. (Is she aware of this debate?)
If this were a vote for us all to play according to the standard rule then of course I would vote for the rule. As Wil says, if he were playing on a physical board he would do the right thing. To me a player who needs a web page to tell them that ... pah!
It would be different if the web page were to explicitly state that either or both dice may be used (though I expect there'd be much concern among the players), but someone who uses an omission as a loophole is skimming close to cheating as far as I'm concerned.
