I don't know, I was asking whether I had understood the parent comment right. I don't know much about name change legislation, and would like to find out more.
I was thinking along the lines of, well, it's not as if any given country "owns" somebody's name -- it's a property of the person, right? As in, you can't have one legal name in one country and another in some other country. That's what common sense tells me at least. But then again I've been surprised by law on several occasions in the past, to say the least...
I know it's at least possible to have variant names; I am legally registered in different countries by parallell names analogous to "Venice" and "Venezia".
Thus spake Eliezer:
It seems that many here might have outlandish ideas for ways of improving our lives. For instance, a recent post advocated installing really bright lights as a way to boost alertness and productivity. We should not adopt such hacks into our dogma until we're pretty sure they work; however, one way of knowing whether a crazy idea works is to try implementing it, and you may have more ideas than you're planning to implement.
So: please post all such lifehack ideas! Even if you haven't tried them, even if they seem unlikely to work. Post them separately, unless some other way would be more appropriate. If you've tried some idea and it hasn't worked, it would be useful to post that too.
