Dropbox Beta Invites
Basically, Dropbox is another online file sharing service that works with both Mac OS and Windows. Check out the Dropbox home page for a screencast and information about the service. Their FAQ page also has plenty of information.
The beta program includes 2GB of free storage...but sign up now because once the beta is over, new accounts (FREE) are currently slated to receive only 1GB.
If you are interested in “beta testing” Dropbox, I have 9 beta invites remaining. I will send them to the first 9 people who request one.
