Don't know if this has already been posted so sorry if it has!
Rafa has just launched an official site www.rafaelnadal.com
It's pretty good, it has some good features - you can email him (although this is more for media etc. than fans)
It's about time the world number 2 has an official site, it's not as good as the fansite www.vamosrafael.com
yet, but it's only starting I guess! It's cool to have a site that us Rafa fans can find out OFFICIAL news about him though!
It's just in English at the moment but it will soon be in French and Spanish also!
