Welcome to Club Fry,
If you have registered to comment on the forum previously, you will need to recover your password using the lost password screen. Our profound apologies for the inconvenience, but for security reasons we were unable to move your passwords to the new website which allows you to comment with the same username on all sections of the website.
If you were registered with the blog, your password should still work correctly.
