Members may log in any time with username (or email address) and password. If this is the first time logging in and you don’t have a password, click the “Forgot Password” link. Next, enter your username (or email address) and press “Get New Password”.
This will send you an email that has a link to reset your password. On the page that link sends you to, you can enter a new password or accept the password that is suggested there BUT be sure to copy and save your password for further reference.
With your username and password, you may now return to the login page for access to the members-only content as well as access to editing/updating your profile page.
