This is towards the admins. When you log on you should be ready to answer questions and respond so dont leave yourself logged on to make people think you are available when you are not. This is why you need the logout timer. Everytime i need to ask an admin a question i get no response, EVER, except for alex a couple of times, but really.
Basically im just trying to say if you're not available to answer questions when your accout is logged on you should either log off or turn your private chat off.
