A lot of current science-fiction and fantasy magazines have online submission systems, accepting Word documents. And where I remember, way-back-when, submission guidelines noting that (printed) manuscripts should follow Standard Manuscript Format, I'm now seeing a bunch of magazines that do not mention that.
One particularly confusing example is that Clarkesworld magazine's guidelines call for standard format, but guidelines to submit for an anthology by the same editor, using the same submission system, do not.
Is Standard Manuscript Format obsolete? Or is it so ubiquitous it doesn't even need to be mentioned?
