Thank you CajNatalie, that is what I thought was the case but I wasn't sure and this place is a great resource.
I built the UN and got the movie, and it shows in the Advisor screen, the only thing I'm not grasping at the moment is when the election happens? Is it when I end my turn, the beginning of the next turn, or do I need to do "something" to initiate it? I know this sounds totally dumb, but I've never experienced this before.
Thanks for your patience.
You don't need to do something to initiate it. After the UN is built the election for Secretary General is held. You, as the builder of the UN, will be one of the candidates along with the AI with the largest population. This election will be held this turn or next turn, I can't remember which.
Votes are tallied with Civs getting votes in proportion to their population. At intervals, the Secretary General decides which resolution will be voted on. If you are not the Secretary General, will be voting on proposals but will have no say in which proposal is being put forth.
If you are the Secretary General, at intervals you will be presented with a list of resolutions to vote on. One of them is a diplomatic victory, but there are several others - ban nuclear weapons, global civics, etc. You click on the proposal you want to put forth. The voting will proceed that turn and you will be informed of the result the next turn. Same voting-in proportion to population. If you are narrowly elected Secretary General, it doesn't make sense to select diplomatic victory - you won't win.
If the global civic is voted upon and the vote is yes, all Civilizations civics will change automatically.
Sometimes, when you're conquering the world and capping a number of Civs, you can build the UN and you and your vassals can force a diplomatic victory by your voting power alone. This is called diplomation, and I often use this to save time when I'm conquering.
Your vassals have to vote for you for Secretary General or diplomatic victory. On other resolutions, they may vote yes or note; their choice.
I don't remember what the interval is. Sometimes it seems to come up very frequently, sometimes it's "when on earth will the next election be held?"
