Im in general quite liberal on new forums. That goes specifically for miles/points program or even groups of such, being FTs core value- and making program specific info easily available.
I dont have the same principle for regions, like Peru. Questions about the Antarctic doesnt really suit other forums so its justified despite low traffic. Peru would as far as I view it, be too limited in volume, and more important have more synergy with South America. Had this been Lonely Planet forums, I would have said yes. In this case I dont see it as beneficial.
