Joe&Barbara:
First of all, Welcome to The Villages!
Explore
www.DistrictGov.org
It will tell you a good bit about the government here, which is really unlike any anywhere else!
And, yes, there is a weekly session designed to tell you most of what you want/need to know. I went the day after I commited to building here. It was very informative, yet, even after having been here for 4-1/2 years, almost, I am still confused, now and then!
Explore what you can at that site, then pose questions here on TOTV. There are all sorts of highly knowledgeable folk who'll tell you all (perhaps even more than) you want to know!
