How can i look available in yahoo messenger all the time even if im not actually online?

You can't actually do it in the way you are thinking. Under the program options, there is a checkbox (sorry I dont have installed at the moment to look) but it says something like show I'm Idle after x minutes of inactivity. This means if you don't move your mouse or press any keys after x amount of minutes, then your "I'm Online" status changes to "I'm Away from Computer" (or whatever you set it to). I think that is enabled by default and to stop that from happening you have to uncheck that box under the program options. But all that is going to do is to do one of two things. If the program is running And If your computer is On, and If your computer is connected to the Internet, then it will always say you're Online. If any of the above conditions is false, then it will say you are Offline. There is no way around it because yahoo is always talking to the server, when messenger is running, to let it know you are connected, have the messenger program running and on the internet. I think it talks to each other every 30 seconds or so. So the instant you exit the program (whether by exiting the program or turning off your computer) or disable your internet connection then Yahoo server will not be able to talk to the program and then will immediately make your status Offline. There is no way to overide that.
