The videos linked below were created to walk the user through general use of the ETC (first table) or provide additional details on specific ETC features (second table). For new ETC users, we recommend watching the "Introductory Series" in the order listed below. For more advanced users, or those looking to learn more about a specific feature, we recommend looking at the "Specific ETC Features" list. All currently available ETC video tutorials are listed on this page.

Also, look out for the  symbol on other ETC pages that link to a relevant video tutorial on YouTube.

The videos below, unless otherwise noted, were recorded in ETC version 1.4. While some parts of the user interface will appear different in these videos compared to the live version of the ETC, the advice and instructions given are still largely applicable.
