The site electronicheckbook.com doesn't exist.
However, if you happen to mean electriccheckbook.com their https://electriccheckbook.com/login has a "I lost my password. Email me" link. Doesn't that work?
Where's your backup?
I've used this website for approximately 10 months or longer w/great success. I have lost my original password and am unable to retrieve it so I'm able to access the account I opened and that has all of my data. I've tried to find a way to contact this site to see if they might be able to help me relocate my account but all I give me is a new user-name and temp password. Can you offer any advice or help in contacting ECB.com? They have everything of mine and I'm unable to get it back.
Any help greatly appreciated.
