To find your digital copies (assuming you have a subscription):-
This may not be available on the mobile version of the site.
Note: We effectively have two websites. This Forum one and the RCM&E magazine one. Logging in to each site is separate.
Go to the magazine site by clicking RCM&E Home (Or right click and choose "open in a new tab" to leave this page open too).
Use the Login box over on that site to log in (Note: most people are getting in using their forum name rather than their email address, and it is case sensitive).
Now here's the tricky bit. You need to hover over the word Subscribe, you'll then see this dropdown.
Choose Digital archive to see the magazines.
