I can see where you’re coming from but I have mixed feelings about your suggestion because:
Chrono and the Chrono forums have loads of things to fix/improve that they haven’t gotten around to and I feel flags would just get thrown in a backlog;
We could just use flag emojis like Pete suggested and
The deals posted usually already have redeem region information provided by the websites/devs/etc themselves on their website.
One thing I feel is part of “forum etiquette” that we don’t always do when posting deals is informing on the title itself which region the deal applies to when it’s not global. Ex:
“[EU/USA] Humble Bundle 50% discount coupon for There’s Poop in My Soup”
Maybe we could remind people to do that or feel comfortable enough about editing each other’s titles when such is the case. Saves time. @delenn13 adds that info to her post titles, as far as I can remember.
Anyways good suggestion but I’m not sure how useful it would be
