[Callers] Wikipedia Contra choreography entry thoughts

Hullo List, Just ran across a Contra dance choreography entry on ye olde Wikipedia. That handy, mildly suspect, group contribution or back-room handled centre for information/ego/slander (pick one). http://en.wikipedia.org/wiki/Contra_dance_choreography It looks fundamentally correct to my less experienced eye and I wonder if anyone on here has already vetted it or at least perused it for validity, which I'd like before recommending it to folks. This is part of a root section on Contra dance which seemingly has more references, though there still seems to be a call for citations. http://en.wikipedia.org/wiki/Contra_dance Thanks, John J.D.
