All the moderators are great and I don't think you can single anyone out. You can't really judge who is the 'best' moderator as you can't see their moderator logs etc. Unless you are choosing who you a good friends with, who you have on your MSN or who posts in the Spam section a lot.
Moderators are there to moderate - obviously,
But, the moderators should have common sense.
Matty has common sense.
BH has common sense.
RD has common sense.
