Accessing the BigOven recipe archive is free, but it requires an email address and a password. You can get your password automatically re-sent to your email address from the "forgot my password" link on the sign-in page, here:
http://www.bigoven.com/resend-password.aspx
NOTE: If an archive password is found for that email address, your password email will be sent automatically, from the account chefmail@bigoven.com, within up to minutes or so. If you haven't received any email, please double-check your Junk Email folder/filters and settings on your receiving end -- many email programs erroneously filter this out as spam. (If no such registration is found, then you did not signup to access the archive using that email address.)
