Death Note Obsession O:

I finally finished watching Death Note, and oh my gosh! I'm so addicted i love the plot, the characters, just everything about it really. I've already decided on my cosplay costume next time i go to my next Memorabilia.. Which remindes me, anyone else going?!
There are a few things I am yet to watch, the movie, L's successors and i'm sure that there is something else too, but i'm having trouble finding these episodes/movies. Every website that has them have either removed the episodes or they just don't work.. Sigh.
I've heard of a character which goes by the name "Beyond Birthday" or "BB" for short. Who is this person? I feel as if i am missing out on something important here.
Geeze, i'm so into this that i'm actually thinking about writing some Death Note stories. Show of hands, anyone interested?

Also, i need new friends :3 Facebook is fun.
