Sorry, I'm not quite sure what I'm paying for if I get this subscription. At present I'm paying $56 per month for Platinum Standard & Platinum Reformed due to dynamic pricing. Paying this for the next 15 months will allow me to keep these resources permanently in my library. If I decide to pay for the mobile ed subscription at $49.99 per month, do I get any FREE resources that will "remain" in my library permanently, even if I decide to cancel after, lets say, 2 years? Or is this more like a monthly "rental" scheme where you never get to keep any resources?
