In my opinion that those contests or events which are already finished and we can't even participate in those events. And those all closed topics that we don't want to open because those have been closed. Due to some reasons. If this is possible in the future, then either delete them all or else hide them. Then it will be very easy for us because then neither the list of pages will get long and neither will we have to scroll down much.
Did I say right and do you agree with me ?
