Recently I have played on my server for ArmA 1 and 2 and I am not 100% sure that ArmA 2 disallows people to come in with mods that I don't have. But I am almost clear that ArmA 1 doesn't... I was just wondering if you guys have any idea on how to fix this problem, because basically ArmA is mod paradise haha!

Second Question... when I play online with people. For some reason my game crashes after about 10 minutes when playing any Warfare mode like Evolution, Domination, Warfare, etc... but it seems to run fine during small missions. One good gesture however, it doesn't seem to crash on my own server. But its overwhelming to me that the game runs 100% smooth online no matter what kind of crash and the intensity of a battle. Its not my hard ware, its my game or my mods. Possibly any suggestions???
