Unfortunately people usually only offer help if they know something about the problem. It looks like you were just unlucky. There is an 'unsubscribe' link on the home page: http://tech.groups.yahoo.com/group/c-prog/ Alternatively, try describing your problem in more general programming terms that don't require knowledge of set theory(?).
