Divided into categories by the collective of func (and others?)
Then selected by a committee, assembled from:
Shambler - long time PlanetQuake reviewer, spot on opinions about all things Quake, eloquent and hilarious. He'll never ever map for Quake but he can very well tell pearls apart from shite.
Daz - put more effort into promoting modern Q1SP mappery than arguably anybody else. Also a skilled designer, maybe not as consistent and prolific in output but he has a good grip on how to judge quality.
Spirit - put more effort into preserving the legacy of Q1SP mappery than, without argument, anybody else. Can also serve as the 'wildcard' judge, with his rather exotic opinions on some releases.
scar3crow - ardent and stalwart fighter for the "Quake was the best game ever made" cause. Has been around for virtually forever, got his mapping cherry popped with func_jam3.
Manages to out-purist even me.
