Most email providers limit the size of attachments you can email. Instead, upload files of up to 100 MB using YouSendIt, and the person you are sending the file to will be able to download it after receiving instructions from YouSendIt. Great for large PowerPoint presentations or videos! And why not download your presentation for yourself just in case your laptop blows a fuse when you get to that important meeting or conference?
