What is a fanlisting ?
It's just a little website where you put your name/nick and country in order to tell all the internet community you're so proud to be fan of any subject !!! Well yes that's all.
There is nothing to win and you have nothing to pay. Fun and simple isn't it great? ^^ There are many many many .... many fanlistings. You could find their address at The Fanlistings.org and for manga and anime related subjects at AnimeFanlisting.org. Since fanlisting are made by fans for fans there is nothing really 'official'. It's obvious that we don't know those actors, directors, creators ... Don't expect incredible things from fanlisting owners.
