Now, according to XenForo, you are reading my message. XF uses this word in many parts of the forum, but if you click "Search -> Useful Searches" you will see "Your posts" which redirects to your... messages? Am I right? I am confused now.
Perhaps the hardest part when switching to XF. Though Nodes is no synonyme for forums, but a parent term for forums, categories, pages and links. In my opinion, using nodes just with the 4 types we have currently is not justified. I wonder if there will ever be other node types.
