Sage Channel News - April 2015 - link to full email - I did not spot anything newsworthy except possibly the revamping if the ATC program to become ATP (Authorized Training Professional). Not sure what you get for that but my first guess is access to training guides. My second guess is you probably get $x,xxx lighter for the fee you pay.
