I tried to sign up, only to find that I was apparently already signed up for that system. I couldn't remember the password. I tried a number of likely passwords, then tried the password recovery system. None of the e-mails I currently have, nor any of those I've used in the past couple of years, seem to work. Now I have a message to the board's administrators, but at best I'll hear back tomorrow. It's frustrating for me, because I prefer to correct these things as soon as I see them.
What bugs me is that Instant Runoff Voting really isn't that difficult. All it does is reproduce how you might vote in an in-person election with a series of revotes when nobody gets a majority. A lot of the "explanations" like the one at which I pointed make things much more complicated than they really are.
By the way, the conclusion the person reached is correct, but not because Hugo voting uses a point system.
