Sorry if this is in the wrong section, I wasn't sure whether it was more appropriate here or in manga general.

I'm used to editing existing series pages when they get licensed, but adding them isn't something I really have experience with, so when adding a new series what's the standard protocol when the author/artist has the same name as another author/artist?

Easiest way is to add a (II) at the end. For example:

Maru

Maru (II)

Maru (III)

Or, if the name in the original language is unique but the romanized is not, then you could do something like

Maru (마루)

Maru (マル)

A just ruler amongst tyrants

Makes sense, thanks!
