Warning, I'm probably broaching a different (but related) decision/brainstorming here.

I'd recommend that everyone reading this topic head over to the front page and just look at it a while and think about how the fora are arranged and the categories and subcategories. (It'd probably be most helpful for coming up with original and creative ideas if you did that before reading the rest of my post.) I'm realizing that there seems to be a lot of disconnect between actual forum content and the way things are labeled and categorized. I have the glimmerings of a re-organization in my mind that would make few substantial changes in the sense that old timers would have no difficulty finding the same forums with a blindfold on, but which would make it far more intuitive and logical for someone trying to find a forum for the first time. However, before I post a rough draft, I'd better sleep on it.

On second thought, there's no reason but pride to present a very, very rough first draft. Basically this very rough draft would pull most of the subcategories of Miles & Points back a hierarchy level out from under Miles & Points. This would cause them to more accurately reflect the fact that the majority of their threads deal with travel on the airline, sleeping with the hotel, or renting a car, rather than necessarily talking solely about the loyalty program. Furthermore, it would make the front page more powerful by exposing each airline/hotel. (It would, however, make it more overwhelming for newbies. That should be a separate decision as I'm sure IB/vbulletin could make top level categories show collapsed on the front page if that would be better for clutter sake.)

Alternatively, in view of the orphan that MilesBuzz has become (and rightly so: it was a conglomeration of Manufactured Spend and Credit Cards and random promos and newbie questions--a combo that didn't belong together. I'm glad they were separated.), perhaps it should be converted to a Newbie Question forum, moved to the very top as a general introduction forum that would include policy stickies and newbie lounge threads and just a general and friendly introduction to FT. Then MR Deals and Hotel Deals could either be put under a Deals category (a bit OCD, IMHO, for just two fora; but it does better represent the way that I browse FT) or they could headline the newly named Airline and Hotel sections, which would probably make more sense for most people. S.P.A.M. would then fit very logically into "Other Loyalty Programs". So that alternative would look something like this:
ETA: One final idea. Split MilesBuzz into the Newbie/Welcome (as done in my second organization above) and a forum that retains the name MilesBuzz. Have MilesBuzz headline a Deals category that would include MR Deals and Hotel Deals. MilesBuzz would then become a place matching its description for the first time in many, many years: "Discussion of the latest frequent flyer & hotel program buzz...only." Basically it would become a place to discuss the mega promos like 36 Avios/$ Nordstrom, 30 WN/$ Sears, 25k Delta Skymall, the amazing Choice hotel per stay promos, etc, etc. It could also host discussions of sweeping changes that may be FFP-specific, but that affect all FFPs. (Obviously if you include the "sweeping changes" part, it becomes less applicable under the Deals category.)

Sorry, lots of random thoughts above. It is 2 am. I hope the above can serve as fodder for inspiration.
