I have been to a couple of the Annual Meetings at the Stanley in Jersey City NJ in the past. It was typically announced that the "business" meeting was held just before the actual meeting. They would say that so-and-so was voted for another term as president, somebody else vice-president, treasurer, etc. At one of the times I was there, I recall Don Adams was the president of the corporation.
Whoever was reading the announcement would try to make it a bit humorous by asking the audience what they thought the numbers were as far as how many voted for each. He (a GB member) would then say, "Believe it or not brothers, there was a unanimous vote of 175-0" (or something like that).Then the people would laugh since everyone knew that the vote would be unanimous.
I'm sure the actual business part of the meeting was very short since who would object to anything presented. It's not like there would be a real discussion as would be typical in many organizations. I just remember that the voting members had to be there earlier (around 8AM) before the rest were allowed in around 9AM. It always started at 10AM.
To be a voting member is just like anything else in the Borg or for that matter, many other corporations. Probably similar to becoming a CO or any other position of power. I just recall hearing that this one or that one was asked by the Society to become a voting member. I do know that a lot of them are older and some need to vote by proxy since that cannot travel to the location.
