This is one of those handy little services that you only need once in a while - but when you need it, you really need it. YouSendIt comes to the rescue when you need to send a large file via email - so large that your email client bounces it back. YouSendIt is much easier to use than zipping a file - you just go to the site, enter in the recipient, and upload the file. The recipient then receives a link of where to go to download the file. It's free up to a certain size file.
