I noticed in the Fossil repository that you are working on limited access threads and I wonder if these are intended for viewing and activity by logged in users, and so not visible without login?
In the opposite sense, will there be a configuration flag to disable adding new threads without being logged in?
Will there be a configuration flag to disable new logins?
If my understanding is correct then these features would provide the private forum capability that I asked about early in July in this post (15455).
A new forum database with the configuration flag set, followed by registration of all intended users, then disabling new registration would result in an empty thread list display until after a valid login. The limited access threads would then be visible.
Hope I've got the correct understanding.
