Sorry I didn't come back and confirm this as promised -- and doubly sorry if people have been sweating hard to get stories finished -- but we did decide on a 2 day extension here as well as in the 75 worder. We just didn't get around to doing anything about it...The Challenge is open until the 31st anyway, and there's a real possibility (which we'll know for sure tomorrow) that the limit might be extended in view of Chrons being down so long.
So that means the deadline is now... um... *counts hurriedly on fingers* 11.59 pm GMT 2 November. I think.
