If you have a webpage and you want to let visitors contact you via email, you have to include a link with your email address. There can be two major problems with this: one - you may not want to disclose your email address to everyone, two - if your web page is listed with search engines, then it is most likely constantly scouted by crawlers collecting email addresses for the purpose of sending out junk mail.
This feature allows you to open an account, and include a link to this contact page with your username, allowing visitors to send you email without ever disclosing your email address.
