in their own words:
It was, and is, a gathering place for the Looking Glass Fan community to come and celebrate their favorite games together. Since its humble beginning as a little known two man effort, the site has grown to a network of five independent (but still part of a greater whole) sites, and a well equipped staff with a wide range of talents and goals.
Going strong since '96, it is easily the biggest, and best Thief forum.
More of a resource site.
