what is the meaning of MOD? what is TLQ? im confuse

First and foremost, allow me to address the nomenclature of DBO (Dragon Ball Online). A majority of the races' subclasses and quests within this game are associated with acronyms, the most common being the following:

TMQ = Time Machine Quests, the missions that haven't yet been implemented by Daenose, but he will once the pre-open beta is over (from what I know). These missions are associated with going back in time to fight the most significant battles in DBZ history, such as the battle with raditz, the saiyan conflict, and the latest TMQ being the battles before frieza transforms. Unfortunately, since the game is no longer being developed, there will no longer be additional content.

TLQ = Time Leap Quests, the missions that allow you to obtain skills such as ki-charge, shielding, dashing, etc. They typically involve you going back to kid goku's era, and completing a short task to obtain the skills.

A "MOD", is short for a modification ie: A method by which the game's data can be modified and altered to fit the wants of the individual. A majority of the mods available on these forums are visible on your computer only, and typically include asthetic changes such as different textures on dogi's, different colors of dogis/textures, etc. There's even a mod to have ssj hair all the time!

Any of the subclasses within the game are frequently labeled with two words, which can easily be shortened into two letter acronyms, for example:

SwordMaster = SM
Karma Majin = KM
Shadow Knight = SK
Dark Warrior = DW
Karma Majin = KM
.....
Fighter = BestclassinthegameMLG20infinity
