Sorry lefteriskatakis, I have to correct u on this one XD
You are right in saying that the CO2 window is a client. It is the visual window which you see and it communicates to the Server. It isnt a medium to the game server, it just sends information on your mouse, or keyboard inputs to the server which enables the server to check, and send back information to your client in which you will then see a visual conformation.
An example of this is when you kill a monster, when you click on the monster, your client (CO2 window) is designed to send "Melee" packets to the server which will contain your character information and where you are in comparance to the monster (thus archers and taos can hit long range because the server accepts their character information, and wars and tros hit next to monsters). The server will then calculate damage which you give to the monster in accordance to your character level, attribute points and Equipment.
Once the server has "authenticated" this information it sends back information which your client interperates and sends a visual confirmation (Such as seeing how much damage you hit on a monster).
Now, Artmoney is as lefteriskatakis has explained but if you try this method of scamming you will see that it does not work anymore. This has been explained in many scamming posts and in this section to be not working anymore because TQ put commas inbetween your money "numbers" (100,000,000) and other clients cannot see that you have confirmed "OK" to sending money to them, even though you can see that you have confirmed sending money (This is all through the trade window XD)
Hope that helps everyone a bit on artmoney and how the Conquer Client functions between the server.
Hiyoal :)
