English only. I used to be a builder for sign language as well growing up. And I know a little Spanish, but I think it would be wise to extend this language because of the United States' current demographics/cultures. (Especially here in Metro-Denver)
Well...I speak English and Vietnamese fluently, but I am learning Spanish right now. Just like Kworb, I'd like to pick up Japanese, but the rest of my family is fluent in French.
Eu sou fluente em Português, lógico :P (I'm fluent in Portuguese, of course)
I speak English almost fluently
Hablo un poquito de Español (I speak a little of Spanish)
und ich lerne Deutsch (and I'm studying German)
