#2 sipa 640 commits#3 gavinandresen 484 commits
#4 theuni 330 commits
#5 TheBlueMatt 288 commits#6 jonasschnelli 223 commits
#7 luke-jr 199 commits#8 gmaxwell 133 commits#9 fanquake 117 commits
#10 MarcoFalke 112 commits
#11 jtimon 106 commits
#12 petertodd 91 commits
#13 cozz 70 commits
#14 sdaftuar 65 commits
#15 morcos 55 commits
