Dave and/or moderators: I’m fairly sure that there’s a problem when anyone externally tries to access a specific forum topic or post. I think any specific link to such content fails to work (almost as if there’s a global indexing problem).
For example, if someone cites a link to the specific topic regarding the proposed changes to the VRT commission, that thread is inaccessible (irrespective of whether the person trying to read it is a logged-in forum member or not).
Put it another way…the only way to access content is to search for it / navigate to it from within the forum. It’s no longer an externally-accessible information source (or so it would appear).
