This is another very handy site. Not everyone has an FTP site to upload files for their friends and sometimes hotmail's 1MB size limit just doesn't cut it. The site below will hold the file for 48 hours (and 48 hours only) and you can email the link out to everyone you want to send it to.
Go to Dropload and drop a load of bites with an email address, and it sends an email to the recipient to come pick up the load. Free and free of the limitations of email servers.
