I think it will be a question for Spark. When Kershaw/Kai wanted to close up it's forum, it was shuttered and moved to the archives as the business no longer wanted to employ moderators to govern the space. Cold Steel, however, is still around even after being sold a few years ago. No real moderation staff has ever been put in place and that forum keeps chugging along.
I'm biased, but in my opinion, as long as someone wishes to greet the door and spin the yarns of those no longer walking the halls of the cantina, I wouldn't see what letting this place stick around would hurt. There is a wealth of knowledge that shouldn't be lost for what little resources as place like this takes up....just my opinion.
