Here's an idea that might help...
Include the TravelBuzz section on the Miles Forum as well as the travel forum, maybe even listing it second on the list. (OMNI is handled this way.) To be able to access these "catch all" categories without switching forums might (at least for the time being) help in the process of sorting out these posts.
Or you could award 50 frequent flyer miles when you post in the right category.
(By the way, this last suggestion brings this topic back within the purview of MilesBuzz...yippee!)
