The Mailinator
Heres something very worth bringing to the table.
This article is very funny and helps a lot if you get all the way to the end. Its goes against making up a stupid new account somewhere else just to sign up for something. (having a seperate email for spam)
With this thing you can make up a name, get what you want and the account deletes itself in a few hours. Pretty handy and saves you a lot of aggrevation.
Check it out.
