Numerous internet surfers probably know the following process: you’re surfing a website and you find a link with an e-mail-address. You click on the link, which begins your odyssey-like journey through the depths of your computer. Why? Because the link leads to the whirring of your hard drive, as the mail-client installed on your computer stirs to action (or, possibly, asks to be set up) and all sorts of additional windows begin to pop open on your screen. Even though you had just been comfortably surfing through the web, now you have to master strong currents as you fight off towering waves.
