Getting published in an academic journal without holding or seeking a PhD?
wheels: Usually it helps to have a co-author that is established in the field.  I didn't do graduate work (and undergrad was in CS) and have one publication in physics and another coming up in biology, but in both cases there is a university professor on there as a co-author.In blind peer review this isn't a strict requirement, but it will help you put things in the right language and help you make sure that you're referencing the right things.
