An Error Has Occurred

We use a security system called CloudFlare to help protect the website from malware, “Denial of Service” attacks, and other nasty things. 99.99% of the time it works great. But every now and then we get a “false positive” and somebody cannot access the website, even though they’ve done nothing wrong. If you’re reading this, that’s probably you.

The most common reasons this can happen are:

• You’re using a browser the system doesn’t recognize or your browser is configured in a way that makes CloudFlare nervous.
• You’re connecting from an IP address that has previously been used for malicious activity. (That doesn’t necessarily mean it was you!)

If you believe you have been inappropriately blocked, please send us an email at [email protected] so we can assist you.

We certainly apologize for the inconvenience and hope you will return soon.
