How do I create an account at Mailinator? It's simple, you just send email to it. Temporary accounts are created when email arrives for them. First, you give out the mailinator email address you created, and then you check it. It's that simple.
Do I have to sign up? No sign-up, you don't even have to tell Mailinator you're coming.
What email address should I use? Anything you want! You can be firstname.lastname@example.org, email@example.com, or if you're a 16-25 year old male you can be firstname.lastname@example.org. Just make sure your "anything" is followed by @mailinator.com.
What can I do with the email address? Give it out. Use it in webforms. Post it on forums. Use it any time you need an email address, but don't want to be slowed down by the sign-up process or spammed for eternity.
Then what? How do I check the email? You have several options:
