Some of the people that I missed are:
-WPM (Can't forget that guy - how he gets around and annoy everyone else )
-Alec Travelyn (Is that how it's spelled? I remember that he's one of the reason why TCG board was popular back then)
-Evil Mewf0ur aka Asylum (He's still here, as far as I know, though he remains as a lurker now - and I think he perhaps hold a record for writing a load of fics in the past)

Other who I didn't get to know much, but still missed their presence:
-Hanada Tattsu
-Iveechan
-Agent Elrond
-The Rusted One
-Pancake
-And a few fanficcers that I can't recall their names (I remember there's one guy, he had the most... weirdest-and-random writing style, like he write the typos in his fic on purpose or something)
