That can actually be quite difficult if there's nothing that you can reply to.
You could end up sitting for a couple of hours or so checking the threads to see if there's anything you can say in a reply. On lonesome nights, the only friend you make is the F5 button...
I remember those days... I used to talk with !K_A! on instant messanger and refresh Zelaron ALL DAY just to reply to particular threads and posts. The good ole days.
