I found some install instructions on the mine craft forums here. I am reaching out to to see if some one can explain to me what steps I need to take in order to install a mod my son would like on the minecraft server. As with all other game servers each server type needs to have different files & directories manipulated in order to install mods if the game allows it. I have run many FPS type servers in the past such as CS, CSS, TF2, BF2, BF3, UT2004 etc. I am new to minecraft actually im running the server for my son, so I have ZERO knowledge of the directory structure.
