I tried sending an email via the "Contact Us" clickie. I type in my email address as requested but I get the message "this email is not in our database". I've changed email addresses a few times and probably since I registered on this site. Therefore, in the database is probably an old email address that I don't use. So how do I update my email address so that I can use this "Contact" form. Thanks!

Above your post you'll see a line that starts "Logged in as: twogypsies". To the right of that, click "My Controls". That's where you can change your email.

If you have trouble past what HappiestCamper told you then send me a PM with the correct information.

My recomendation is just to re-register

my controls, as HappiestCamper said, and it is under options. Change email address.
