I really don't see a point in it. I mean, you want the well-behaved members who would qualify for an invite to something to "spam" away? lol, kinda contradictory isn't it? plus, I've never seen The Den as spam central. it's merely off-topic from TLK, with a dose of randomness thrown in now and again. I certainly haven't noticed any more spamness to it than the other forums, aside from topic(s) specifically for randomness which is there to get that spamming need out of our systems. there are a broad range of topics that aren't on-topic to TLK that would be just fine there. afterall, there is a whole huge world out there away from our beloved movie
plus, this isn't a turn-off for members. the TLK-only forums usually struggle on with activity because sometimes even TLK fans get bored with talking about TLK ALL the time. off-topic areas enable the members to take a break, as well as get to know more about each other outside of the TLK realm. it's kinda like the watering hole of our site, I suppose you could say.
