For the upcoming season of the World Shuffleboard League, which starts on October 1st, 2011, the official rules have been modified.
Thanks to the feedback from many players the WSL Board was able to identify situations that could be improved.
Following rules have been modified:

5. Each team shall be required to submit a minimum of two scores every two months and a total of at least six scores for the season. Any team that fails to submit at least two scores within the stated two month period, will receive a “0” (zero) score for any missing score. A team may submit as many scores per month or season as they wish as long as the minimum requirements are met. However, only the last ten scores submitted shall be used. All scores must be submitted at least 15 days before the end of the league season.

8. An individual may be a member of no more than two WSL teams.  If a member elects to be a member of two teams, at least one team must be an international team with a minimum of two foreign players.  Separate scores must be shot for each team.

11. Team averages and ranking shall be posted on the ISA website and seasonal winners shall be declared. The three teams with the highest average 14 days prior to the end of the season shall be invited to participate in the Play Off Series. If one or more of the invited teams decline to participate in the Play Off Series, subsequent teams in descending order shall be invited to participate. The Play Off Series (“Finals”) shall take place during the last two weeks of the season. In the finals each team has to deliver three scores under the supervision of a WSL Board approved referee. Winner, 2nd, and 3rd place shall be determined by the higher average scored during the finals.
