Experience has taught me to recommend a role sheet for all the meetings. In other words, state who attend each meeting. You can even go to the extent of stating the arrival time and departure time of each member. This role sheet can serve important purposes in the future if there is a dispute of who did what and who did not do what.
Also, have one member keep track of the discussions in the meetings. This is important because it is easy to forget the action items and conclusions in a meeting. A tape recording is fine, but reviewing/replaying a tape can be more troublesome than just reviewing points in a plain text file.
