Hi 7PLAIN,
First you have to send an invitation to Pinterest, then they will reply to you to confirm your account.
Then ,yes, you can create a Pinterest account using an e-mail address and password or if you prefer you can login in to it using your Facebook or Twitter account, if you have one of course!
I hope it is clear! See you on Pinterest!
Ciao,
Dario
