This is nearly the perfect online storage solution - secure transmission of files, a free 5 GB starter account, fax services, and an easy-to-use, well-designed interface are just some of the great features. The only drawback that I have been able to find is the inability to tell what files one has sent, whether via fax or email. (Also, there appears to be no way to recall an email or cancel a fax once the fax has been scheduled.)
