Hey I am new and the only reason why I am on here is so I can get an answer for my question. My question is how do I use mods when making a gameranger server for jedi academy for me and my friend? I know you guys might help with this cause I see a post on how they had a modded gameranger server.(sorry for how short this is I had to write this three times cause I pushed backspace it takes me back to the last page I was on)
