Other rule changes enacted in 2000 include the introduction of the
let serve which allows play to continue even if a served ball touches the net as long as it continues into the opponents' court. Also, the service area was expanded to allow players to serve from anywhere behind the end line but still within the theoretical extension of the sidelines. Other changes were made to lighten up calls on faults for carries and double-touches, such as allowing multiple contacts by a single player ("double-hits") on a team's first contact. From 2006 there are plans for trying new rule changes, such as having a second serve option when failing the first (as in tennis ) or a second alternative libero in the team.
