Error Tracker

historical tracking of all known errors

Our Error Tracker is a live real-time data silo that lists all known reported issues with our products. You can easily save and print this information and use it as an "Errata Sheet." We depend heavily on user-reported submissions for the data compiled in our Error Tracker.

Error Reporting

Notify us of a discovered error.

We only know about an error if you report the error. Even though we strive for perfection. Rarely is anything ever completely perfect. If you find an error in our content, have a critique, or want to see something changed. Please voice your feedback with a submission. Your submission will generate a support request on your behalf and someone will reach out to you.
