I miss Wesslewoggle. He was a disturbing, creepy dude but he kept me entertained. Sadly, he was permabanned a while back (didn't he call ioi a mudmonster?). He came back last year as TheEvilBanana, but left shortly after.
Patapon was another fun member on here. He was one of my favorite comedians on here. His joke in a Heavy Rain thread 2 years ago will never be forgotten.
TrasharmDsister12 seems to have left also, so I'll give him a mention. I liked his sense of humor. I wonder what he's doing now. Hope he comes back.
Dsage01 was a good dude too. There wasn't anything really special about him. I don't know why I liked him really. I dunno, hope he comes back. I still remember his Head-to-Head series he hosted last year. It wasn't a well put-together series (he made God of War vs Gears of War, simply because they had the same initials), but was still fun nonetheless.
There's probably more that I can't think of right now, but I'll add them later. What about you?
