I can think of more interesting things to debate.

If you don't mind people knowing your first name, fair enough. If you do, fair enough. There's not much more to it. I think it's an interesting way to shake things up (though obviously it doesn't change much for me personally) and given the diversity of the online JJ2 scene it's an opportunity to learn about other languages as well :P

But in this day and age I can understand if people want to share as little personal information online as possible, or prefer to be called by their self-chosen nickname. To each their own!
