ghost forum 

A message board that is still online, but is practically deserted, save for a small group of people who still visit it. Normally there are large amounts of broken links, and any topics not on the front page are a few years old.

Armageddon Games Forums is a ghost forum, it's still around but it's slowly shrinking away.
