The Holy Land of Marturion, a newly developed nation, is seeking information on any International Sports Leagues, preferably football, soccer, basketball, or ultimate frisbee. If none exist The Holy Land would be interested in meeting with other countries interested in developing such leagues. The president himself has shown interest in participating in several of the leagues, if permissable.

There are many sports, many of which are featured here (http://www.nationstates.net/forum/viewtopic.php?t=90716&highlight=)
Unfortunately, you've missed out on the beginning of football World Cup 12, which is about to get under way, but you can sign up now for World Cup 13 (http://www.nationstates.net/forum/viewtopic.php?t=121740&highlight=) now!
Also, there is the Richter Classic Basketball (http://www.nationstates.net/forum/viewtopic.php?t=118914&highlight=) you may be interested in.
I know not of any ultimate frisbee tournaments. Perhaps you could set one up, I don't know.
