Firstly, would suggest you do away with using the FL abbreviation before you've defined it. Ideally a post clarifying abbreviations should not use those abbrevaitions except when clarifying.
Alterations
codies, can only be bought from Armouries.
GC, Golden Chrysanthemums, not Gloden Chrysanthemus
KoS, Kill on sight. the past tense would be KoS'ed
ooc/OOC, missed a few letters in roleplaying it says "not roplaying his/her part in server"
Traditionally PC and NPC mean Player Character and Non Player Character, but you're current definitions fit well
rep, Indicator should be changed to Indicates
Rep fixing, "means making the reputation to align with current character/faction" remove the word "to"
Shield Camping, "you continue with attack" should become "you continue with the attack"
Additions
LH Lane Hackers, whilst it is the player faction it should be added as it's used to define Lane Hacker NPCs
LPI, Liberty Police Incorporated. Again it's a used acronym for the police NPCs within Liberty, especially New York
Okay the bat wasn't needed, this is not me attempting to belittle your work just an attempt to iron out any wrinkles. Hope this helps.
I press Del. Ok, I might hate you for a couple of minutes, but after that childish bout I truly thank you for the time you took (that really I should have taken in the first place) to read through the dictionary. I know my Achilles heel is that I'm too lazy to proof read anything, since every line and sentence is perfect the second I write it down. The proof reading is for incompetents and illiterate. No wonder I spend half of the time later correcting my own posts since the sentences/thoughts don't make sense at all.
