Please also note that despite some discussion to the contrary, Wuala appears to be very safe and secure and your data is well protected:
Wuala protects your data and guards your privacy.
Wuala is the place for storing data with security in mind. In order to protect your privacy, Wuala encrypts the data on your computer before it is uploaded. During the upload, your data is split up into many different pieces and stored in multiple places to make certain that you never lose a single file. For added security your password is never transmitted, which means that no one – not even the employees at Wuala – can see your private files.
