Some of the more active members, yeah. If I've worked with them then I definitely remember them. There's also some of us who hang out at irc.quakenet.org #cplusplus. I tend to know them a little better.
People in italic I feel like I know the best amount about their skills and posts. This list basically comprises of people who 1) Post a lot and 2) I have seen over time giving generally good answers/discussion.
*Sorry, I probably missed a few people out off the top of my head. =/
Well I might as well introduce myself. I am mainly a Java programmer with knowledge in many other languages. Mostly Ada, Go, Python, TCL, C, and Assembly. I have a bit of knowledge on older processors like the 6800 and the 6502. One of my favorite points of study is network security. Aside from that network design and IT security.
I remember that helios was the first one who answered my first question on this forum, then Duoas, Bazzy, firedraco, Disch, guestgulkan.. yeah, they answered a lot of my questions since 2009.
Oh, and I remember there was a guy who always told everyone to "ask advice on win32 newsgroup" or "avoid external libs and everything but msdn samples/tutorials".
