Lets you post files of up to 1 gig, Automatically sends an email to the recipient giving them a link to the file. Deletes itself after seven days. Free. Brilliant.
Yeah - that's why I thought it would be good here - 1 gig opens up to a to much more video stuff. I think Koz jammed up his work's FTP site once with a 1 gigish file for me - to have it hosted remotely would have been even better.
