Apart of those ~ 3000 we have some specials members, like grcpool and pomegranate. We should at least count in grcpool members as they are aware or conscious (in contrast to zombies from pomegranate).

So whats the reason for the huge RAC increase, whitelist changes or new crunchers?

• more active members (including growing populations in pools)
• hardware upgrades

..... ah joking, main reason is growing charm of science :D
