How did the meeting go?
It is always useful to get feedback on how the meeting went.
One way of doing this is to ask people at the meeting what they thought of it. You can do this at the end of the meeting. Just ask each person in turn how they thought it went. You will get some useful feedback, and it makes everyone feel involved. This tends to work best with a small group that meets regularly but can also be useful in other situations.
If it is a big public meeting, you might want to have comments or suggestion forms for people to fill out at the end of the meeting.
