Why did you use echo?
he's using /echo -t; /aline doesn't have a -t switch. there are also a couple of side effects of using /echo that are desirable in a script such as this: the window label changes to the 'event' colour indicating to the user that information has been added, and the line can potentially be logged to a file if the user chooses to log the window. just because /aline can only be used with a custom window does not mean a custom @window should only ever use /aline.
That way, it actually takes less CPU.
this is baseless nonsense.
