Local meetings that hold Meetings for Worship generally hold
meetings for business once a month, and are called "Monthly
Meetings." The Monthly Meeting usually deals with membership,
marriages, paying rent, etc for the meeting facilities and/or
real estate, etc. Monthly meetings sometimes have one or more
"Preparative Meetings", which do business with the monthly
meeting, but meet elsewhere.
