This is a part of our Cambodia forums to chat about anything Cambodia-related. This discussion forum is at the top of our site because it's usually the busiest part of the expat community chatter with random topics on just about everything, including expat life, Khmer politics, Cambodian blogs we have or have come across, or whatever else our members want to discuss. Whether you're an expatriate, tourist, Cambodian or random traveler just passing through South East Asia, you are welcome to talk about anything or start new topics yourselves.
I know what you mean, and I think those subforums don't work until you have critical mass from the particular city, however you'll never get critical mass without having the subforum to start with. The forums are very Phnom Penh-centric. If someone has a question like, "Where do I buy cardboard boxes?" if they are in Phnom Penh they can ask on a forum, but if they aren't, they will ask on Facebook group dedicated to their city. Maybe it's okay to leave it that way, or maybe it might be worth trying to lure some of those Facebook users over here.
