Saw this in ' LJ:

Javier Grillo-Marxuach (), writer and supervising producer of LOST, and all-around excellent person) will donate $5.00 to the American Red Cross Katrina relief efforts for every person who links to his post.

Just link to him, then comment in his post that you linked.

(And for the record, Martha Wells writes really cool sci-fi/fantasy novels and you should all buy her books. :) )
