The veterans of Switzerland’s English speaking forum know more about renting accommodation than the officials. They know more about the paperwork, more about residency permits, more about recent scams and more about going rates for accommodation
They simply know more than the people running the country.
The only viable option for the Swiss government, and your company, is to endorse these people. Bring them in to you. Ask how you can support them. Send people to the forum. Highlight the best posts. Create monthly unofficial guides from the top content. Recruit moderators as volunteer advisors.
Official recognition is a wonderful gift. It only means something to those that care. To the people that care it means everything.
