/b/, /d/, /g/, /m/, /s/ /x/, /z/.
/b/ = bloody (new board for normies)
/d/ = dirty (formerly /s/cat)
/g/ = gurochan (formerly /dis/)
/m/ = morbid (formerly /g/uro), because *morbid* curiosity
/s/ = strange (formerly /f/reakshow), you can call it /w/ = weird if you want
/x/ = legal precedent, you can call it /L/ if you want, that'd be funny
/z/ = furry (formerly /fur/)
That'll be 8 boards instead of 13... That's like 5/13 ≈ 34.8% less work!
