We often come across situations wherein we want to receive a message by email but don't want to give out our email address; and think it would've been better if there was an alternate URL which can be shared in place of your email address. Well, whspr! is one such service where it creates a url from the email address that you provide. You just have to place the whspr! URL in place of your email address. This temporary URL would last for a minimum of one day and a maximum of 365 days (which means you can choose the number of days of its activity).
