I think this argument is easily settled.
INF Online: It all comes down to consideration.
A veteran has the consideration to not exploit bugs, such as the lean bug, or auto-prone.
A newbie accidently exploits a bug, but stops after being informed of the bug, and that it is considered bad form to exploit it.
A n00b does it after being warned 5 times and pleads "1 d1d|\|t no!!!!"
Inf Forums.
A n00b can be anyone, regardless of how long they've been here, or how many posts they have.(remember, theres a difference between free speach and cheap talk.)
Deathren is probably a good example of this. Credit to him that he's cleaning up his act, but we have to look at his history. He's got quite a few posts under his belt, and has been here a while. He still acts/acted (depending on how you look at it) like a 12yr old. This makes him a n00b.
A newbie on the other hand, is someone who has only been here a short while, yet still behaves reasonably maturely, doesn't post porn, or pretend to be a pothead.
A veteran knows the ropes, knows the various mental issues that most people around here have, behaves themselves in a courteous manner (doesn't mean they can't flame total idiots *coughDjLethalcough*) and actually knows that 2.80 wasn't the first version of Inf released, nor was it as good as it is now.
Simple. No?
