Hi,
Someone else does the actual conversion process, so I don't know if they use QDoc or something else do it. However, if that is an important detail I can check it.
I find broken links quite regularly, with every release of software, and users don't tend to report them, they will just now and then say things like "Your documentation is no good, there are lots of broken links", but without remembering any specific ones (I can't blame them, I would probably do the same!)
I will subscribe to the Interest mailing list as you suggest.
Thanks
