Very useful; every time that you come accross a website that “asks for a registration”, and damn, the only thing you want is to download that creepy damned free book, or free software, or free MP3, or demo of whatever, and they ask you for all your life for the nth time.

Just go to http://10minutemail.com/10MinuteMail/email.html and get your 10 minute e-mail. It works great, and you get what you need. No more problem with filling forms online!
