How about experience and acceptance by professional publishing companies with specialty magazine publishing and distribution in this, our chosen area of favor?
With respect, you are opening a can of worms here because everyone who is not a publisher will vary in what they presume is a qualification.
Everyone who is or has been an editor or publisher is looking for knowledge, experience, credibility in word presentation and supporting pics and hopefully the last 2 things would be professional presentation which minimizes the need for time in editing manuscripts and lastly, continuity, or the ability to keep it coming, encompassing all of the above.
Having a particular specialty in an area of technicality or experience is another plus.
I would be very interested in knowing your thoughts on qualifications, and I mean that sincerely, without malice.

When truth is ignored, it does not change an untruth from remaining a lie.
