To post comments at the end of frogblog posts you need to become a registered user. This is a very simple process which requires you to submit a valid email address and reply to a confirmation email. Go to the registration form.
When you register you should choose your email notification preferences. By default all registered users are subscribed to the daily digest, so if you want to receive emails when the posts are made, or a weekly digest, or no emails at all make sure you change the the pull-down menu.
When you click the register button, a temporary password will be emailed to you. You can use this password to login. After you have logged in the first screen you are presented with is your user profile page – you can change your password there.
If you forget your password click the Lost your password? link at the bottom of the login page and enter your username and email address. A new temporary password will be emailed to you.
If you forget both your username and your password: you have to register again with a new username.
