Just register for their upcoming webinar. All attendee's receive a free PTSv3 course. It will probably be barebones, but for those who are curious about their setup and what the training might look like, here you go.

The promise of the free course was in the email, but I don't see it on this page. Might still be worth checking out for some of you.
