Interfederation

An interfederation is a community of e-federations which choose to become part of it, often by the founder's decision, or by a roster vote. Interfederations run several multiple federation events, such as tournaments, and tend to have most of their activity based around their forums.

The best-known interfederation is Primetime Central, which was founded in around 2001, and has been open since (with several different owners). Most others have closed over the years, with interfederations such as Fedwars and HOTv proving to be short-lived. Currently there are only a handful of federations, with Projekt Xero being the closest rival to PTC.
