Sorry if you have tried signing the guestbook in the past few months. There was a problem caused by spammers and it was just brought to our attention. We've now password protected the guestbook, but it is only to keep robots out and not the public. If you don't know the the username and password for emails and bios, you can use the one provided below.
You may have to enter your username and password twice. It your browser gives you the option to save that information it is recommended that you do so for each time you are asked to sign in.
