[Organizers] dance group structure (resending)

sorry, i sent this under a different email address so it was held for approval. i am resending under the correct address. i am interested in hearing about different methods of dance group organization. i am aware of two basic methods: 1) elected board method, which is responsible for making all decisions by vote and 2)the beneficent dictator method (b.d.). the b.d. may or may not have people that act as a board who are appointed, but in the end all decisions are those of he b.d. re: elected board voting methods: there are a couple of variations for the voting process: 1) dancers get the right to vote by buying a group membership, or 2) whoever is at the dance on the day of the election gets to vote. (my feeling is that regularly attending dancers ought to be the ones voting, but i haven't figured out a good way to track attendance) a side issue of the elected board method is how the positions are established, sometimes individuals run for positions (eg president, secretary, treasurer, booker, etc). in other groups a certain number of people are elected to the board and the board decides the different responsibilities. are there other methods or permutations? any comments on the pro or cons of these different methods? thanks, Jeffrey
