I am no longer affiliated with a University. In the instance that I publish a paper (co-author or otherwise), is it appropriate for me to e-mail my old University and ask them for a staff e-mail? This journal is highly ranked. I don't know how the University rankings work so maybe they will look favorably upon this if more publications under that University's name means a higher ranking expectation.
I used to have a staff e-mail but they destroyed it when my contract terminated.
