5th gen oldbie maybe?
1st gen = remembers pre p2p, when all was free (javagraal+graalv1 era) 1998-2000
2nd gen = remembers when it was free but had p2p servers (v2 era) 2001-2002
3rd gen = remembers when all went p2p and introduction of v3 linux and mac client (v2.3-4 era) 2003-2005
4th gen = remembers when observer mode was added (v5 era) 2006-2008
5th gen = Graal###### acc era 2009+
I might be wrong about the years.
EDIT:
iPhone players that started playing when iClassic came out are calling themselves oldbies now. DO YOU FEEL OLD YET?
