Correct Client for Server

[William]

I'd let the server send a string to client, instead of the other way around. It's harder to edit incoming than outcoming packets, I think.

Might be, I dont have any knowledge when it comes to snipping up packets. Why not have it both ways then. With different codes. So if the client code is correct, like this example. It send one back again Kinda useless actually since if the first check is correct, the client is correct.. but still.
