Interesting I have been a subscriber to Model Engineer for well over two decades and as well as having the magazines delivered I used to have access to the digital copies. I say "used to" because whilst I had paid for access to these, now that my subscription to the magazine has lapsed I no longer have acess to what I had previously paid for.
I must admit I have not read the terms and conditions, do Digital subscriptions only provide acess to the 12 month window that you are paying? Other on line mags you continue to get access to what you have paid for even if you don't later re-subscribe.
