What Makes A Community?

There are just so many right answers to this question, but I'll try to break it down to the five that I think are the most crucial for a community to exist. I think that in order for a community to exist, there needs to be communication so that members of the community can interact and discuss things/interests. But in order for communication to happen, there must be people that make up the group that communicate. I think people are the most important piece of a community. In order for the group to form a community and exist in an orderly environment there has to be some sort of rules established. There also needs to be security for a community to interact so that the members can feel that they are safe. Also, reproduction is important for a community because there needs to be a way for the community to grow and not just disappear after the first generation. These five properties are the best foundation for a group that comes together to create a community.
