a real world point of view
Gallifrey Base, or gallifreybase.com, is perhaps the world's largest online Doctor Who forum. It is sometimes considered the unofficial successor to the forums previously hosted at Outpost Gallifrey, since it is based in the United States and arose because of the demise of OG. However, there is no formal relationship between the two, other than some commonality between the day-to-day administrative staff. It is loosely affiliated with the Doctor Who News Page, the successor to OG's news page.
