The votes were counted and the ones with the highest votes were accepted as UFO's nominations for their categories and then LorD, Crash, Hooty and Saber discussed the nominations and, rather subjectively decided upon the winners.

You can hear the final awards ceremony podcast here and the discussion that got them there, here , but for your reading pleasure and easy reference, the full list of nominees, with winners in bold is available after the break.
