Ugh. It is much simpler for us. The clerk takes the minutes (summarizing points made), writes them up and after approval at the next meeting files a copy in a binder for the future. I added the Treasurer's Report to the binder copy, but it was generally pretty easy. I think once the minutes ran to three pages, but usually it was just one or a bit more pages (at 11 point type). I think maybe once in 4 or so years did I ever get a call about something in the meeting.
How large is your Vestry? We have 9 members.
Our vestry is comprised of 12 members who serve 3 year terms. A member may serve a total of 6 years consecutively, before they must, according to our by-laws, retire from the vestry for a minimum of one year.
The Rector's Warden, Accounting Warden, and Secretary are all members of the Vestry. I don't know if that's a rule, but that's how it's worked out for the past couple of years.
