Submit to Kasma!
Kasma SF is currently open to submissions.
The magazine accepts articles or stories around 500 words that are concept-based. The idea is each piece is a mix of concept that could be, but is actually fiction.
For example, tricorders in the old Star Trek. They were used for communication before cell phones were common place. This probably lent some feasibility to the suggestion that one day we could have portable communication devices, even devices that translate, etc.
Up to 500 words please. Payment is $25 (CAD) per accepted article/story.
