First off, your privacy is very important to us. We will always work to keep your information safe and secure, and we will never give (or sell) any of your information to any third party without your express consent unless required to do so for safety or legal reasons, as parts of a sale of our company, or as may be necessary for us to provide our services to you.
We are always available to handle your questions and concerns. If you think there is something fishy with your account (or the site in general), you should send us an email right away. We'll look into it as soon as possible.
Okay, now that we've said all that, keep in mind that this is still the Internet, and there are a lot of people out there looking to do bad things, some with a lot of resources. Because of this, you should never put things like your social security number, date of birth, or other identifying information in this system. You should also make sure and choose a strong password for your account so that it is more difficult for anyone trying to hack into your account.
This is just good practice on any web site.
