Thanks for getting back to me Jeff - I know that is an option, but it has several downsides:
it will erode the value of our lovely short healthforum.nz domain name - this is of course where our instance resides. We could of course get around this by having the pages in a subdomain such as info.healthforum.nz/faq
the existing really nice navigation within faq / about / tos / privacy (and now guidelines oddly if FAQ is redirected) does not work for anon as they remain stuck with just tos/privacy
there isn’t a facility to redirect /privacy or /about in order to have the whole bunch + navigation outside of Discourse
Surely there is a way to make those two pages (and the navigation links to them) visible to anon with a bit of theme customisation. @awesomerobot, your topic here looks to contain the building blocks that I would need (I think) - please let me know if I am barking up the wrong tree!
