I would certainly be willing to help judge under the conditions Hans
describes (11 games in first round, 6 in finals, no judge evaluates any
group including their own design at any time). It seems the best way to
manage the rather large field.
For the newly-opened 43 squares contest I have gone to a two-round
preferential voting system, as the task is getting quite large for one or
two judges. This contest was also originally slated for voting, so a jury
of the public is a reasonable return to what Fergus originally conceived.
