@nadja Thanks! It's not really about impressing people, and I don't really like to list my languages. It's just that I have difficulty focusing on one thing. I'd probably be fluent in a couple more languages if I could do so.
I should've divided them up more... there's ones I am somewhat capable of forming sentences in (Arabic, Turkish, French, Italian, German, Ido, Interlingua, Brithenig, Klingon), the ones I can read without much effort but can't really form sentences in without help (Catalan, Interlingue) and the ones I have an extremely rudimentary knowledge of (the rest). The one I know the least is Thai.
I also forgot to mention Lingua Franca Nova (I'm capable of forming sentences in this) and some others I thought of over the last 24 hours, then forgot.
@alter_kaker Oh great! Excited about the language forum.
