Yes, but the delivery schedule on Book 5 used to be mostly what you would talk about in the Martin sub-forum too, wasn't it?
One of the things we worried about is that if we got rid of the sub-forums, the popular ones would then swamp the main forum with too many threads on the same authors because the sub-forum conversations would be moved over. That was the original reason for creating the sub-forums in the first place, and we figured if it happened again, we'd have to put the sub-forums back. But that hasn't happened this time, which is sort of interesting.
So I suggest that since finding old threads and continuing them still seems to be an objected to practice in some quarters, despite the valiant efforts of our tag squad, squashing discussion it's felt, that we definitely let people just start new threads on the authors. Brighten up the place, welcome the new folks, and put the author's full name at the beginning of the thread title so it's easy to spot. If we run into repetition, we'll deal with it, but since repetition has not so far occurred, let's open the floor.
But -- and this would be my other suggestion -- you'll get more conversation if you're less forceful about dissenting opinions. Old talking pals can josh with each other, but new folk are less inclined to join the conversation when they're going to get sneered at for liking/disliking Jordan, Martin, Erikson or Goodkind. We've had several new members complain already that they find it difficult here because it's all secondary world fantasy, because only a handful of authors get talked about, and when you do try to talk about them, you get jumped on. So apparently, you're scaring them off from talking.
As for your old talking pals, I suggest PM-ing them and asking why they won't talk with you about Erikson and Martin no more. Bug them if they're quiet. Because I'm not sure that putting back the sub-forums is going to magically get them chatting again.
Again, if it isn't working so well, we could experiment with putting one or two sub-forums back if the staff and owner decide it's workable. But the lack of a discussion does not make a good argument for setting them up again.
