The ins and outs of Club Extensions
Club Extensions (or satellites) offer members and prospective members a way to create a new club experience together, as a smaller group supported by an established local club. The Extension club is an offshoot of a sponsor club, which serves as the governing body of the Extension club. 
An Extension club can form with only eight members and usually meets at a different time and location than the sponsor club. They pay dues, hold regular meetings, organize service projects, and have their own club leaders. Sponsor clubs, on the other hand, provide advice and support to the Extension club through frequent communications. Members of Extension club can come from the sponsor club or they can be members new to Rotary.
