Irregularity: 8 November. Our 'Age of Reason' anthology for next spring, with the National Maritime Museum. I do not care at which point on 8 November I receive stories, but be aware that there is a limited window between "receiving stories" and "going off on holiday with no internet access to a place where I will be reading the stories". So wiggle room there ain't.
Pandemonium: The Rite of Spring: 15 December. Loads of time - I had initially scheduled this very late, so folks could read Ash before writing. But Ash fell early, so, hey, take advantage of it... six weeks left to write 750 words for our next chapbook.
And one more - a big one:
The Kitschies. 1 December. This falls on a Sunday this year, so if you are a publisher and you are sending physical copies, you'll want to keep that in mind... We do take digital copies though, which might be convenient for some. Publishers should get in touch at firstname.lastname@example.org. Authors and agents should nudge their publishers (they love it, I know).
