The International Softball Federation (ISF) holds its 26th ordinary congress in Cartagena, Colombia this week. Representatives from around the globe travel to South America for the gathering from October 21 to 26. Current President Don Porter will be challenged by Dale McCann during the elections. Prior to the actual congress on Friday, October 25, all the commissions and continental confederations will meet. Full Program. It is most likely the last ISF Congress, as ISF and the International Baseball Federation (IBAF) have formed the World Baseball Softball Confederation (WBSC), which will be holding its inaugural congress next March.
