By community we mean a person who (1) you can reach directly, and (2) is interested in following your project. This community can be activated to support you with regular monthly financial contributions. About five percent (or more) of your community members are usually willing to do so. Members of a community usually have a commonality, such as age, profession, hobby or social engagement. There may be clubs, NGOs, associations, foundations or companies you can reach to grow your community, or you can use newspapers, newsletters, Facebook groups and events. Perhaps there are personalities you could enlist to promote your campaign. The size of your community is hard to measure exactly, but you can make a rough estimate.
