EVERYTHING IS SO SIMPLE, JUST FILL THE FORM AND MAKE YOUR OWN E-MAIL ACCOUNT.
It will look the next: firstname.lastname@example.org
WHILE THE SERVICE IS NEW YOU HAVE A UNIQUE PRIVILEGE TO PICK UP THE SHORTEST AND THE BEST NAMES FOR YOUR E-MAIL ADDRESSES!
(Don't let somebody else to sneak out your favorite names!!;)
The service is called reliable, because it is backed with a strong Internet company. That means IF this webpage would disappear one day (what is absolutely improbable) the unique address you gained through this form will continue to be valid for the rest of your life! There is only one chance to lose it - if you abuse it (like SPAM, PORNOGRAPHY and so on...) or if you don't use it for a half of year (what is more tolerable rule then 30, 60 or even 90 days in other services similar with this one).
