I am a hardcore Tolkien fanatic, and have been posting on Tolkien message boards since January 2002. Currently I am an active poster on The Lord of the Rings Fanatics Forums (which I think is the best Tolkien community overall on the web by far), where my user name is Ardamir .
My essays on Tolkien Gateway:
E-mail: jolin at abo.fi or jumppa at gmail.com
MSN: jolin at abo.fi
IRC: Ardamir on Tolkien-Gateway (in #Lore and #MinasTirith)
Or if you are registered at any of the Tolkien boards above, you can send me a private message through them.
