Your suggested rule of thumb regarding 5 active threads is also a valid one.
J.D. more or less summed it up. It realy requires a sustained momentum of interest over multiple threads from a number of users to have half a chance so to speak...Were you considering the 5 thread rule as a "suggestion" or as food for thought re doing it differently? I have to admit to sometimes wondering why certain authors are still on the list and others have never jumped through enough hoops to qualify.

The bottom line is this: Author forums are meant to be a convenient way of organizing threads so that fans of a particular author can find them. If there aren't any active threads to organize, there's no reason to start a new forum. It's not a matter of jumping through hoops, it's just showing that if a forum existed it's likely that people would continue to post in it.
Though what rules exist that governs whether a sub-forum should remain, I cannot tell.
Personally, I think this forum might have a tad too many subforums, most of them very sparsely populated and rarely updated, which discourages viewers and posters alike.
I now have an active Dan Simmons tag, so if you click the link in his name you'll find other discussions of his works. I'm beginnig to think that this way will work better than a subforum.
