Here are some information about fanlistings and Rem.

Fanlistings?
An explanation by thefanlistings.org:
'A fanlisting is simply an online listing of fans of a subject, such as, a movie, actor, singer, video game etc (in this case Remu (Rem)), that is created by an individual and open for fans from around the world to join. There are no costs, and the only requirements to join a fanlisting are your name and country.'

Remu (Rem)
Taken from Wikipedia:
Rem is the Shinigami who first gives Misa her Death Note and "eyes." Similar to Ryuk, Rem possesses two Death Notes; however, she purposely gives a Death Note to Misa. Rem inherited her second Death Note from Jealous, another Shinigami who died when he saved Misa's life, and thought it only right to pass it on to Misa. Oddly enough, Rem inherits Jealous' love for Misa as well and is prompt to defend Misa even at the cost of her life. She shows this when she openly shows her lack of trust for Light stating that if Misa dies before her time, Rem will kill Light. Rem died after she was tricked by Light into killing L and Watari to protect Misa.
