I'm kinda bored so I want to create a kind of timeline for the global server, not just a timeline for all the patches or whatever but a timeline for everything that significantly affected the community. My memory kind of sucks, so if everyone can contribute, maybe we could make a great timeline for whenever we want to immerse ourselves in nostalgia 
I'll start off with some examples, but remember, my memory is horrible.
Sometime in '04: Omg an actual patch notice that's not a more complete version
April '05: Ossyria strike at Ellinia station
A bit before May '05: Split into global and Maplesea
May 11 '05: Official release, 2x exp for 2? weeks, lots of deaths on the ship to orbis, lots of people stuck in El Nath
December '05: Highly anticipated third job, complete with Wizet's horrible preview
February '06: Ludibrium!
Summer '06: Zakum with the stolen Legend of Zorro ad, lol, hackers hog Broa's zakum for a long time, zakum jump quest hackings
Summer '06: Aqua, and nexon surprises us with aqua dungeon like a month later (lots of pianus suicides and hackings)
November '06: Nxgames -> Nexon
Late '06-Early '07: Huge hacker epidemic
Early '07: KFT and removal of channel 20, hacker no-tolerance policy
Summer '07: New Leaf City: excitement and cheap potions, hacker epidemic (etc explosion)
The patch after that: Himes, everyone angry because himes don't drop pyogos
Late '07: Autoban gets rid of almost all hackers
October '07: Halloween, non-nx users can't get into mansion, NLC becomes Nexon Loves Cash
November/December '07: Pumpkin Vault ruined, Black Friday/White Christmas AP reset sales cause frustration
November '07: Pumpkin pie quest, dragon knights roar the crap of Henesys hunting ground 1, subliminal messages in the 100/250nx quest, massive rollback event, 2x exp compensation
December '07: Herb Town pq, tons of complaints for not having any high-leveled content for almost a year, 4th job promotion leaked
January '08: Lots of anticipation for 4th job, 4th job is released
Early '08: Powerguard hack (level 30 warriors at skelegons), shop/dupe/fame/guild hacks
March '08: Tespia wave 1
April '08: Horntail released (killed in a couple of days and promptly monopolized), Tespia wave 2
June '08: 24+ hour patch, Tespia wave 3
Summer '08: Nexon keeps on missing the 2x exp compensation for missing the compensation
July '08: Mixed feelings about the strongest boss being a cute pink thing
August '08: Huge bigfoot controversy, elemental weapon controversy
I've obviously missed a whole ton of things, so just feel free to post. Remember, this is only a timeline of stuff that deeply affected the global community.
