It's kind of mean to label the whole Den as one big "spam" forum.
People have important announcements to post there, and The Den is pretty much the only place we regular members can goof off and have fun and talk about anything we want without worrying about whether it's off-topic or not. Take that away, and MLK's a strict, nazi TLK forum. New members wouldn't be drawn to that. Sure, we love TLK, but sometimes we gotta just take a break and talk about something else for a while lol. If I were a guest lurker, I'd actually be
more drawn to the site because it has an off-topic section.
And as Azdgari said, I can forsee many disputes that might result from this...
