Once you have submitted your information without problems, your temporary password will be emailed to you. Make sure you are not blocking mail from bobrost.com.
Your information (including email address) will not be given or sold to anybody, and I will not be spamming your email myself.
Your password will be stored on the database as a salted hash, which means that you can safely change it to the same password you use for all your other random logins. Just ignore that the http connection itself isn't encrypted.
