Another thing...Why did the elves not fight?

[Etharius]

I was pretty dissappointed at the elves in story of LotR. They didn't fight at Helms Deep or at Minas Tirith and neither at that other place. I think they are either wussies or stuck-up. Why were they not prepared to sacrifice themselves for the destruction of Sauron and the ring?

And the same goes for the Dwarves, although, i can understand those fellows.
