A site created in 2001, Bordersdown has over 11k members and over 1.5m posts. I took ownership of the site in 2008, along with maintenance and development, the main challenges being server and database performance with such a busy site.
It allows the staff to post Articles and Reviews, but the main reason for the site is for the audience to chat with each other in a Forum about their hobby. It normally has 100+ people online.
