I agree with Piratecat. However, I also think that a sticky thread would be completely suficient. When an author finishes a Story Hour, they can post in it. There wouldn't really be any need for anyone else to post in the thread.
But, I also know that most authors - like myself - put such information in their sigs. Not that everyone reads my sig, of course. I also put the fact that it is completed in the Thread Title so that it is visible from the main Story Hour Forum screen.
The only honest perk of having a Forum for completed Story Hours would be that they wouldn't get pushed back to the rear so quickly. They would stay on the front page for much longer. After all, Story Hours don't get completed every day around here.
On an aside ... anyone know how many completed Story Hours there are? And by completed I mean totally finished, not abandoned in a good place to stop.
I've got one. El-remmen has a whole portal full of 'em (what, 5 or so?) I think Lazybones has finished more than a few ... Wulf has how many? Shemeska certainly has to have some that have reached conclusion. Blackdirge? Jollydoc? Others? Just curious.
