    Is it possible to download a copy of the two (EPA) presentations videos that we could use in MA for trainings.



    • Hey Ken – the two videos are posted to our YouTube. Rather than attempt to transmit such large files via email, I would recommend using a free online service like or to download the videos directly to your PC. All you need to do is navigate to the videos online, grab the URL for each, input the URL into the field at the top of one of those webpages and it will ask what format you wish to download the video. …this is a cool trick for capturing a local copy of any video you see on YouTube.

      If that doesn’t work for you, feel free to follow up with me – aderosa(at) I can provide you with download links from one of our cloud-based file-shares.
