IANATBM, but I think you moved it to the right place. If there were a forum dedicated to discussing the general discussion of earning/buying/redeeming points/miles with absolutely no context of how/where specifically to earn/buy/redeem them, I think that post would go in such a forum. But I also think such a forum would mostly garner crickets, as it's obviously not a very common discussion topic (hence why you're asking).

If we start to see a large influx of posts fitting the description I made above, I think a new forum might be necessary. But considering how long it's taken to get this first one, it might be the year 2205 before we need that new forum.
