could someone that knows how to do add-ons for fs2004 please give me some advice on how to add stuff to my game. i've downloaded lot's of airlines and planes and put them on the game, but i want to know how to make the traffic airlines instead of the default airlines. i also downloaded the co-pilot thing and lot's of other stuff, but i don't know where to put it all. could someone that knows about this please tell me how to make my flight simulator as real as possible?? example, real airline traffic and any other cool stuff that you can help me with. i am in the army right now in iraq, and planning on pursuing my airline pilot career as soon as i leave iraq, so i want my fs2004 to be as real as possible so that i can get a feel for how it will be. any and all help will be greatly appreciated. thanks. you can e-mail me any suggestions or comments to troy8u2@aol.com. thanks again!!!
