I agree with TheIvanMuse: I agree. The Dens were a great way of saying "Here is a great member who is friendly, contributing, and fair" and removing them just means that they're being stripped of their reward. Also, the reward of a member den made many members (including myself) want to post better and be a part of the community more, in hopes of one day earning a den. And what's removing them going to do? I know it would open up more space but (personally) I'd rather have a section dedicated to great members rather than another section for games and such.
Again, this is just my opinion. I don't know exactly what would replace the Dens, "games and such" is just my guess XD
