I posted this earlier but didn’t see it come through; perhaps it got eaten.
I’ve installed RTFM and it works fine – for privileged users. Unprivileged users can’t see it at all (when one logs in, there’s no sign of RTFM). I’ve enabled all the rights I can think of that make any sense (and then some – all the RTFM rights except the Adminxxx and Show/Modify ACL, same for the Class and the Custom Field I’m using) and still no sign of RTFM for unprivileged users. What am I missing?
