For me, and in terms of SFC related ITK-ness: Essruu, VFTT, FloridaMarlin, THEVMAN. For basic enjoyment of the forum and those who actually get the idea that its a place for a bit of p*ss taking and being taken the p*ss out of from time to time: CBFry, SmirkingSaint, Turkish, DogDog, BearFeatures, Tokyos and probably a few others who I'm too lazy or carefree to mention right now.
