I am not quite sure how thread tagging works with automatically generated threads from RSS feeds and automatically generated threads from add-ons (like XFRM and many others for example). I experienced tags automatically assigned to a thread when they were set up in the specific forum node and then I had threads that missed to have the same tags although they were assigned to that node. How does it work, or better, what are the prerequisites to have automatic tagging working smoothly with system generated threads? There are so many parameters that might influence each other. Permissions do influence this too?
