MikeJones I believe the link to the user list is currently not added to the sitemap at all.
I'm not sure if/how we want to handle pages added by other extension. We could either provide an extender for other extensions to register themselves and use that in each other FoF extension with custom page, or hard-code all compatible extensions inside of FoF Sitemap. Currently only FoF Pages is integrated with sitemap that way.
We could also potentially inject all registered routes into the sitemap, which would theoretically support all other extensions automatically, but the problem is that this will likely inject pages that aren't intended for guests, or are only for mobile, like
/settings. Also it's not very useful if the page update time doesn't have a custom implementation for each kind of page.
