Here's a pretty easy way to share a file for free. I think u can send up to 10 MB per attachment, 100 MB total.

1) Set up a free Yahoo! email account at http://mail.yahoo.com

2) Choose a username like firewiredemo

3) Choose a password like firewiredemo

4) email the file as an attachment to firewiredemo@yahoo.com

5) All of us can log into that account by going to mail.yahoo.com and using username firewiredemo and password firewiredemo

6) We all remember not to delete the message, lol
