Mod

The term mod may refer to several things:
 * In-game items, such as class mods or grenade mods (etc)
 * Modified (modded) items which have been edited to change their stats or add attributes not "naturally" found on an item.
 * Modification, player-made software add-ons that can include new items, weapons, characters, enemies, models, textures, levels, story lines, music, and game modes, etc.
 * Moderator, user with additional control on the Official Forum. This term is sometimes used to refer to sysops here on the Borderlands Wiki.
