AnimeForum's community has the right to form its own nation, as does anyone capable of meeting the terms for establishing one made at the 1933 Montevideo's Convention on Rights and Duties of States.
Article 1 of the 1933 Montevideo Convention on Rights and Duties of States defines a state as possessing a permanent population, a defined territory, a government, and the capacity to enter into relations with other states. Article 3 of the same Montevideo Convention specifically says that "the political existence of the State is independent of recognition by other States." Therefore, AnimeForum could form a country if they were willing to.

I will not participate in the forming of such a nation, but what might the rest of you think of this?
