Edit: I tried to avoid posters that I think still post on these forums but I'm not really sure who does and who doesn't.
cklistie - He was my partner in crime who actually read my god awful dynasty stories and shared my huge man-love for Trevor Ariza and Marquis Daniels. I could've sworn they were going to be multiple time all-stars.....
Jona/Drex/Jonex - Who could forget when these two paraded every single thread posting simultaneously? Great lulz were had from this pair.
Cyanide - He was a mod here for a while who I think did a great job and treated everyone with respect. Does he still post?
Colin - Canadian dude who knew a lot about rap. Super jelly of his really cool looking Phoenix Suns avatar.
Kevin or KD or w/e - Another Canadian dude who was pretty cool
Cableguy - Another Canadian back when Canadians actually were a pretty big portion of NLSC aside from Aussies and Pinoys.... He was typical laid back, funny guy that I enjoyed reading posts from.
Maguis - Kind of a troll sometimes, but he made some pretty good posts when he wanted to
Bighort - Popularized the

Jowe - Made some pretty sick patches for NBA Live 2004.
Nick - He was another one of the few people who made an attempt to talk to me on MSN (which were probably failed attempts because I was socially retarded back then). Funniest guy at NLSC at the time for me. People typing in bold purple text will never be the same.
The Goat - Wasn't he like this 12 year old kid who was hella gangsta or something? Anyway I remember him being pretty chill at times.
Jugs - Another 12 year old who looked like Luke Ridnour in his rookie season. Another one of the few people to add me on MSN. We had some pretty funny chats every now and then.
Fenix - Tom Cruise pretty boy who seemed pretty cool, don't remember too much about him though
Riot/Indy/BhzMafia - I lump all three of them together because the amount of fanboyism for the T-Wolves/Pacers/Grizzlies was astounding. Every post in the NBA section was guaranteed to stroke the dick of their hometown team.
