Broken Index link in Reference

How do I get to the Index on Reference web page?

The link on page is broken.

Hmm good catch, actually there is no index to that. That particular link refers to a different index on the publishing platform and should be completely removed. The catch to all this is that the reference manual is going to go through another major rewrite here before long as it is updated to A3 so I am unlikely to spend to much time on it(Primarily to not having any time right now).
