[Liverwiz]

If you're wanting to do something to a client that is steamID specific. Do it at client_authorized. If you're looking to do something to a client that has connected, and you want to make sure has joined. Do it at client_putinserver. This is not necessary, as they can be interchangeable. But it is important to know the difference if you're trying to do something that requires that specification. (like a vault data grab or flags assignment)
