A particularly successful form of multi-stakeholder cooperative is the Italian social cooperative, of which some 11,000 exist.  1 Type A social cooperatives bring together providers and beneficiaries of a social service as members.
The sport of Quidditch gets its name from Queerditch Marsh, the location of the first recorded game. A witch by the name of Gertie Keddle lived on the edge of the marsh around the year 1050 and recorded what she saw in a diary that survives to this day.
This results in six games of Quidditch: 1  Gryffindor v. Slytherin. The first match of the year, normally held in November (PS, CS, PA, OP), but moved to the end of the season in PA (see below). 2  Hufflepuff v. Ravenclaw. Held at the end of November (PA10). 3  Ravenclaw v. Slytherin. January (PA12). 4  Gryffindor v. Hufflepuff.
