that you would not accept an appointment for permanent host?
In my 4 years of taking part in these contests I have not seen a host intercede and pre-emptively attempt to solve what could be a real problem. Vigilance and responsible hosting at work. For what it's worth, I'm very impressed and I'm learning, should I ever host again.
The thought of being permanent host actually scares me a bit. So, I'll gladly pass off the hosting to the winner and let others gain some experience (or if it's an old hand at hosting, then some experience with DU3, not that there's much difference). I'm sure there are others who can (and will) do a better job hosting.
(I am flattered by the suggestion, though.)
