Old School Derby Association
The Old School Derby Association (OSDA) was an association of roller derby leagues in the United States. The OSDA was founded by Kenneth Sikes in 2007, with nine member leagues. It has the stated ambition of bringing together innovations in flat-track derby with the traditions of the banked-track sport. It uses a rulebook developed by the Penn Jersey She Devils, which can be used for men's, women's, mixed or alternating groups of skaters, and for play on flat- or banked-tracks. The OSDA was initially described as one of the two main organisations for derby leagues, along with the Women's Flat Track Derby Association (WFTDA). The ''New York Times'' described it as being known for "allowing tougher, more punishing hits" than the WFTDA. As of 2013, the OSDA is defunct. Leagues In September 2011, the OSDA listed six member leagues:Leagues

Roller Derby
Roller derby is a roller skating contact sport played by two teams of fifteen members. Roller derby is played by approximately 1,250 amateur leagues worldwide, mostly in the United States. Game play consists of a series of short scrimmages (jams) in which both teams designate a jammer (who uniquely wears a star on the helmet) and four blockers to skate counter-clockwise around a track. The jammer scores points by lapping members of the opposing team. The teams attempt to hinder the opposing jammer while assisting their own jammer—in effect, playing both offense and defense simultaneously. Overview While the sport has its origins in the banked-track roller-skating marathons of the 1930s, Leo Seltzer and Damon Runyon are credited with evolving the sport to its competitive form. Professional roller derby quickly became popular; in 1940, more than 5 million spectators watched in about 50 American cities. In the ensuing decades, however, it predominantly became a form of sports e ...

7 (seven) is the natural number following 6 and preceding 8. It is the only prime number preceding a cube. As an early prime number in the series of positive integers, the number seven has greatly symbolic associations in religion, mythology, superstition and philosophy. The seven Classical planets resulted in seven being the number of days in a week. It is often considered lucky in Western culture and is often seen as highly symbolic. Unlike Western culture, in Vietnamese culture, the number seven is sometimes considered unlucky. It is the first natural number whose pronunciation contains more than one syllable. Evolution of the Arabic digit In the beginning, Indians wrote 7 more or less in one stroke as a curve that looks like an uppercase vertically inverted. The western Ghubar Arabs' main contribution was to make the longer line diagonal rather than straight, though they showed some tendencies to making the digit more rectilinear. The eastern Arabs developed the digit fr ...
