The important thing is that people generally feel happy with what actions and stances you take as a group. If they don t, they ll get frustrated and lose interest. Finally, remember that having a democratic structure is not enough.
Democracy is a way of life.
You should be constantly encouraging people to participate, give their input, and feel a part of the group. The idea of consensus is that you talk about it until pretty much everybody agrees. The down side of this is that a few dissenters can paralyze the group, even when the vast majority endorses something. Then again, a simple majority vote has its drawbacks too. Remember the importance of respecting a diversity of views.
