I stumbled across this website yesterday and decided to join today. I suppose I could be considered an "original" fan as I read the books of LotR before the films, but only just before, and partly because the films were being made, so perhaps it doesn't count.
My real name, by the way, is David.
Lindir was a Rivendellian Elf, "possibly a minstrel. His name means 'One-who-sings' in Sindarin." (The New Tolkien Companion, J.E.A. Tyler, 1979) I don't know where in Tolkien's works the name comes from, but I was searching through that book to find an appropriate name; and I liked the name Lindir.
