Some of you are not getting your passwords quickly. This process should not take much time at all. If you don't get your password promptly, please check your spam filters, and junk mail boxes. Perhaps the mail is being interpreted as junk by your email server.
If you still don't have a password, please sign up again.
If your password is not working, it may be because you are keying it in incorrectly. This is very easy to do and I recommend copy/paste. Once you get in, you can change your password to something easier for you to remember.
