Lol another one
(I really wonder how many elvish threads there are by now... I counted them some time ago, but i forgot it again)
Erm- ok.
Which sort of elvish - Quenya? Sindarin? An other Eldarin language?
I think Quenya, right? (looking at your name...)
So
Best site ever concerning elvish is
www.ardalambion.com (probably most linked site in this forum lol)
You find a Quenya course here http://www.uib.no/People/hnohf/qcourse.htm
And a quite easy and interesting Sindarin course (including Tengwar writing) here http://home.agh.edu.pl/~evermind/mathom/pedin_edhellen_en.zip
