Dropbox is very easy to use. Install it (2gb free larger storage space for a fee), create an account and start saving files. You can also share these files with others, both dropbox users and nondropbox users.Sonnet Ireland at UNO is an expert dropbox user.
I have an account but have not used it much. Sigrid and I are interested in what Dropbox users are sharing and with whom they are sharing. I will contact Sonnet.
