Active community participation is key to building an empowered community. When it comes to the Planet Chiropractic Classified ad System, participation is not a requirement, but it is critical to community success. For many users of the ad system, participation is equals browsing advertisements, posting ads, contacting buyers and sellers, and basically using the service as it was intended. While that’s great (and we are thankful for the amount of user activity the site receives) I’ve been impressed by the stepped up participation, particularly among sellers of private equipment.
