If the minutes of a previous meeting are published then people will know whats happening.. if those and the agenda for next meeting are published then people might make an effort depending on the subject at hand.... just an idea
some wont want to go about one thing but might make a special effort to attend about somehting else..
keeping everything secret just makes a mockery of the whole thing.. the "you should be there" line doesnt work... look how many members abroad? let alone as bottletop points out the people of accy who simply cant get there..
