I'm really curious as to know when you'd use participancy over participation. Right now Chrome is telling me that participancy is wrong and not a word. I always believed it to be a word and it is in http://dictionary.reference.com/browse/participancy as a word. Would someone be able to help clarify the difference between to two and some usages. Apologies if this is an obvious question, first post here.
Just to update you. I am a native uk english speaker. Thanks for your answers so far
