Thanks to Simon Whaley for letting me know that the editor of Allas magazine has confirmed they WILL consider stories which have been previously published outside of Sweden. He's also the man we have to thank for providing an English translation of the guidelines.
Hmmm, wonder was his music collection looks like?
There's no need to translate the story as they accept submissions in English. For UK writers Allas pay £100 direct into your bank account.
Submissions should be sent to lotta.gustavsson (at) allas.aller.se
