Correct; WERM isn't on there, but it teaches everything you need to know to do commercial. (Riffle force & click change). So I'd say the WERM is the only thing missing.
You can download specific 1-on-1's that are from the Trilogy, but you cannot get the Trilogy material itself via download; it has to come through the mail. Most of their stuff is worth the $5, but that would add up really quick...
