Hi there I've just registered I'm new to online play for RA2/YR. I was wondering where the best place to play online is. I have gamespy arcade installed and I think you can play on there. There is also the system within the game I've never used. I don't think I registered when I installed the game and I might not have installed the shared internet components either. Can anyone help in getting set up? Also, can people cheat or is the system fairly secure? Thanks
