What controls the length of time for which a thread 'headline' is displayed on the forum opening page?
I ask because I've noticed that some threads to which contributions have been made quite recently are
not headlined in the top-level forum page, whereas some threads which have not been contributed to for
some time are still displayed. For example, threads going back as far as May 11 are still displayed, while
threads contributed to as recently as 48-72 hours ago have 'disappeared'.
Not particularly bothered (the 'missing' threads are still available, if looked for) - just curious.
Thank you.
