Hi Jim,
1) Yes, public pages are available in M:N!
2) We are still working on our documentation for M:N and do not have anything for public pages yet.
3) Public pages are just app pages that you have made public. I’ll explain how to do this below.
4) But they are :)
To create a public page, simply create an app / page the same way you would internally in M:N. Then from the edit app screen, select the Security button.
Uncheck the “Prevent from being shared publicly” checkbox and select save. This allows anybody with the URL to the page to access it.
Now for generating the URL; You will need to use the “Generate Short URL” action for this. You can create a simple internal page for this. Just make sure that the Invite Type is set to Public.
That’s it!
Anyone who has the URL will be able to access the page. You can also use the URL to insert the page into your website. I believe this can be done using an <object> tag, but you may need to confirm this with your web developer.
I hope this helps!
