I've just tried it and it worked fine when I put my subscriber number in. If anything changes I'll let you know. In the meantime I think it is a brilliant facility and works really well. Even the page turning and zoom abilities work well and actually made reading the magazines very easy.
The only thing I could think of to improve it would be to have a direct access to a particular page without having to turn every page, unless I've missed that bit!!
If pre '07 mags were not digital then you would only need someone to scan each magazine and convert them to a .pdf file. Shouldn't take you too long Colin!!
