Facebook's new profile format emphasizes your multilingualism and a number of fiction's best constructed languages are legit options in their drop-down menu. So far, you can flaunt your fluency in:

• Klingon (Star Trek)
• Na'vi (Avatar)
• Esperanto (various)
• Newspeak (1984)
• Nadsat (A Clockwork Orange)
• Sindarin, Quenya, Westron, Khuzdul, and the Black Speech (Lord of the Rings)

Still missing:

• Huttese (Star Wars)
• Orth, Qwghlmian (Neal Stephenson various)
• Fremen, Gallach (Dune)
• High D'Haran (Sword of Truth)
• Parseltongue (Harry Potter)
• Dothraki (Song of Ice and Fire)
• ...many I've forgotten, I'm sure.

It's just another way to let your geek flag fly. For personal enjoyment, you can also change your Facebook display language to Pirate (avast!).
