10 minute mail
you've probably all run into the hassle of having to enter a valid email address somewhere on the web, just to be able to read an article or access a knowledge base. maybe some of you have set up a dummy address, which you use explicitly for this purpose, and which prevents your actual account from being flooded with spam.
10 minute mail lets you create an email address that will only be valid for 10 minutes. before its auto-disposal, it will display all messages sent to it on the web, and after it, well, it will be gone. (via reddit)
