Email is another way of communicating in the Internet. It stands for electronic mail, and that's correct, it's like mail, but in the computer! Sometimes you get spam, in forums you get updates from them. You can write messages to each other in email.
Email is kinda like forums, except there is nobody to use the ban hammer on you or your friend, but you have to wait and there's nobody stopping you from posting porn, sending viruses, and posting spam.
Email is usually the best way of contacting somebody, since you do not pay to send an email or get an email, except for electricity bills.
