I just discovered that non-logged-in users couldn’t copy content from our website. This was entirely unintentional, and it is fixed now. Sorry about that. We would never do that. The bad news is, nobody told us.
That means that either
a) nobody said anything, and just thought badly of us or
b) nobody is copying our stuff.
As far as we are concerned, both of those are bad news, for three reasons: we want you to interact with us; we never want to send that kind of message; and we want our content to be used. (Of course, we welcome a shout-out for it, as required in the Creative Commons licence).
Anyway, it’s fixed now. Help yourself. Use it nicely.
