Got an invite from a real journal to consider. CitImpFactr ~ 2.5.
My specific circumstances are that I will never be a lecturer and there is no career progression prospect for me (within Uni... unless I move to Admin or support role, I guess). But I have a relatively secure contract and quite like to publish (h-index since 2012 is 14). I thought maybe being on a editorial board would help me understand behind-the-scenes aspects better. But maybe not worth the bother??
I'm curious to hear general reasons for or against, that apply to all other types of Uni researchers, too, such as ECRs.
