Thanks your help.
What should I do this state?
The site hasn' t got irc chat or E-mail.
Who sent the invite isn' t enough brave, to write the admin' s of the site.
He said afraid of, he will get bann. I think this is not true.
I wrote my problem and I translated to Italian language.
If somebody send my letter to any admin on bitvaulttorrent.com I am very grateful.
Thanks.
Some minuter later one of my friends wrote me a letter.
He wrote, I should install Hola VPN web client.
This web client is generated an Italian IP address for the user.
I installed hola, opened again the Web browser (Firefox), opened the registration link and the right side of the screen opened hola and chose Italian language.
After filled my registration part and I apply to join the site.
