Add an Alliances rule:

Occasionally, a country may make a post entitled “Forming an alliance: (Name of alliance)”. In the body of the post, e shall name all countries e is willing to accept into the alliance. E may not include the hegemonist in this list. Each of those countries may respond by this post by stating that e wishes to join the alliance. If, after 48 hours after the post, at least two countries beside the country who made the post wish to join the alliance the alliance is officially formed, with the original poster and the countries who responded affirmatively as its members.

Occasionally, a country may make a post entitled “Request to join (Name of existing alliance)”. In the body of the post, e may state the reason(s) why e should be accepted into the alliance. Each member of the alliance may then vote on this request the same way e would vote on proposals. If, before 48 hours after the post, at least half of the members have voted FOR, the country making the request is added to the alliance.

If a country would be a member of two or more alliances at the same time, e is instead no longer member of each alliance e was a member of except for the last alliance he joined. At any time, a member of an alliance may leave it by making a post to that effect.

Add to the last paragraph of subrule Order Processing:

If the target country and the issuing country are in the same alliance, the issuing country shall not be fined.
