Hm, that's odd...
Anyway, here are a few links, or threads, with the same topic on the Barrowdowns:
Learning Elvish
Elvish Languages
Another Learn Elvish.
Anyhow, all the threads are referring to Ardalambion. If you scroll down just a bit on the front page (Ardalambion), you'll see that the different languages are listed. Quenya and Sindarin are the most complete (correct me if I am wrong anyone) elven languages; there is even a
Quenya Course (Just press this link, or the link on the site).
I hope that was somewhat helpful.
