Legacy is available in 4 versions of English (US, UK, Australian, & Canadian). It is also in Dutch, Danish, and 2 versions of Norwegian. They are currently in the public testing phase for Afrikaans, German, Spanish, French, Italian, Finnish, & Swedish. Lastly, they're developing Chinese, Estonian, and 2 versions of Portugese.
They also support an awesome email list. It's great to keep abreast of what's going on in the software development, provide feedback, add to wish lists, and mostly to learn more of the awesome features.
I would find it helpful if nFS had an email list (that was also searchable on a website for those choosing not to subscribe). Aside from the nFS interface being steps backward in computer programing (i.e.: no hovering; right click is useless; moving backwards in time is pretty simple, but it cannot descend my tree; moving between siblings data takes too many steps; small box sizes cut off names; bolded name blocks the spouse; the top 2/3 of the screen is 1/3 blank; etc.), a user email list where problems can be posted and may be addressed in a timely fashion would be awesome. Having someone call me repeatedly while I'm at work or with clients is not an optimal support system.
