well I do have ayu as my wallpaper:
it's not that crazy, but if you look at the top right..
it's a cheap little countdown timer to the MOON/blossom release ^_^
and right now i'm doing something not really necessary, but I'm going through her TA entries and saving a lot of the pics with her in them..
when I'm on the computer sometimes I'll just have ayu tabs open and refresh them, since I'm now in TA I refresh her diary/news page every 10-20 minutes or so. I only joined twitter to tweet her and don't really do anything else there.
I keep my ayu-tunes pretty organized
my ayumi hamasaki folder is pretty big.. it includes photos, lives, PV's, interviews, etc. her music is in another folder though that's about 17GB
umm idk what else to do to prove i'm a bit of a crazy fan.. i'm not really that crazy though or else I'd have some huge massive collection of every version of her singles/albums like some big fans do.. my collection isn't even that big
but i do have 3 ayu posters in my room ^_^ i'd take pics but my camera sucks.
