I agree with the existing answer but I wanted to add something about this specific question. The Question you refer to is Is there a set of guidelines to indicate where on the neck to play equivalent notes?, and the edit was to render the title as Mandolin: Is there a set of guidelines to indicate where on the neck to play equivalent notes?
I'd say that in this case the inclusion of the name of the instrument, or some narrowing feature, is important. Like the violin the mandolin is usually tuned in ascending fifths (G, D, A, E from bottom to top) and so any "guidelines to indicate where on the neck to play equivalent notes" will differ from those for a guitar (which is usually tuned E, A, D, G, B, E from bottom to top, i.e. in fourths), or a ukulele (with its reentrant tuning where the strings are not ordered from the lowest pitch to the highest pitch), or a 13 course lute tuned thus:
I don't think this is a general question, asked through the specifics of mandolin playing, I think it is a specific mandolin question, and so narrowing the question title to include "mandolin" or "stringed instruments tuned in four ascending fifths" seems useful.
