As i know so far, Unsichtbar dosnt care about his Server Traffic ... XD ...
German guys got unlimited Traffic limits : /
not like me, who got a montly traffic limit : //

Ah well, on the other side i found today a host who offer 100 gig / month. (0,00€ free membership, php, blabla.)
But i dont trust that hoster that much so ill stay at my own webserver 50 gig / month (2,00€, php, etc.)
