World Assembly Members are nations that have been accepted into the NationStates World Assembly through email notification and confirmation. Nations in the WA receive the ability to trade endorsements with fellow region members, vote on resolutions, and, if they receive at least two endorsements, submit their own proposals. Nations receiving the most endorsements in a region become the Regional Delegate.
NationStates players are allowed to have only one WA member, regardless of how many different computers or nations they might have. Any player that is found controlling multiple WA members will have all of their nations ejected from the World Assembly for multiing.
The United Nations had the same rules regarding membership prior to the April 2008, when the UN was replaced by the WA.
