Chao Yang has just launched a new Sokoban website: http://sokoban.org
This new website is for sharing and playing new and original Sokoban levels. Registered users can post levels, submit solutions to levels posted by other users, add a comment to levels, etc.
Levels will be show in image as well as standard XSB format on our new website. So it will be very convenient for users to copy the level into their favorite sokoban programs.
Many active Chinese level authors like gyjgw, tengxi, etc. are going to post their new levels here.
