Most people feel comfortable working in a group of this size. It is not essential to have a leader. Planning can be a genuine group process.
Disagreements have to be worked through for the group to be able to continue.
In intentional community, people often have the expectation of a family-like bond between members. However, once a group gets larger than around 7 people, this becomes difficult. Also, even though a diverse group may have a strong desire to work, eat and live together it is often hard to find consensus between different cultures, age groups, couples and singles. This size equates to several families, and provides increased opportunities for improved economic viability, social interchange, and self-reliance in food. More skills can be exchanged.
