I wish the Story Time forum's index could sort by either "last post by anybody," as it does now, or "last post by original poster." That way you could easily find stories that had had new posts by the original author, if you wanted, or you could find stories that had new discussion activity, as it is now.
I guess there'd be a potential for abuse; authors could post "bump posts" to their own story threads if they wanted to keep their stories at the top of the "last post by original poster" list. Then it would look like they had new updates when they didn't really. I'm not sure how to prevent that other than just warning authors not to do that. Maybe the feature wouldn't bump a post to the top unless it was greater than some minimum length? This is turning into a complicated idea. Oh well, what do people think? (I don't know if it's even possible with the forum software, let alone whether Miss Christie would want to do such a thing.)
