nuqneH, Becky jIH.
I joined as a guest recently and have completed all the guest lessons available (the ones that teach you how to say things like "loDnI'wI' ghaH" and stuff). I have also voted on the chabal tetlh requests. Finally, I've done some reading up on the vocabulary and trying to learn the 4,000 or so words of Klingon. I hope to learn more of the syntax and morphology.
Does anyone have any recommendations of other things I could study that don't require a credit card?
