The forum is here for such thoughts
Indeed, the 'yes, but' is there, the work and pay-off is difficult. We'd have to have someone set up the forum locally, write integration code, update PBF to allow for an API-key to be accepted, you'd have to generate and distribute an API-key, and then we'd have to make sure that all stays working as the game evolves (which means setting up some automation, deploying that forum with the prerelease automatically, doing some testing around, perhaps manually). As you can see it's regrettably not quite just plug and play (so to speak )
It is a long term vision though for games to be 'cloud-save' capable and for stats to be recorded with players. In this case case there would be results pages viewable in-game, and by player. I think missing from that is just the concept of a clan.
It's a far-off effort, I hope it gets done in the next year or two. @ScratchMang is the suggestion about right in terms of what you're looking for, that it would fit your use-case if the stats were simply in-game?
