I must confess I semi-frequently resurrect necro threads for various reasons.
sometimes the question has never been answered.
sometimes I wanna throw in my 2 cents
sometimes I don't even realize how old the thread is
as far as locking old threads goes, how long before there are more locked threads than unlocked ones?
as far as deleting threads goes, what ancient archaic valuable information may be lost in the mists of time?
I am however in favor of deleting or perhaps merging (if that's possible) duplicate threads.
for example: exactly how many "change KB to KD globally" threads do we need?
