User and developer comunities (2)

The developer community will only be formed and maintained if the people has a reason to belong to it; the community members can be paid workers or volunteers, the first group can belong to one or multiple companies interested on the project and will usually keep working on a project as their daily work, but in a lot of cases the work is done by volunteers on their spare time, so they have to feel that their work is taken into account by the project leaders
