Do you think themed issues of ST might be a good idea? Just mooted the idea with a friend on Facebook, and came up with the following themes - curses, witches, monsters. Obviously ghosts are another possibility. Would a theme be too restrictive, or might it stimulate authorial creativity to re-examine familiar tropes, ideas, imagery etc? Also, might themes be extended to include more general terms like 'islands' or 'travel'?
Over to you.
