Communities and Partners


If you are confronted with a rare disorder, you will look for others who share the same experience. And for people who know more about it. When you get into contact with each other, a community is created, first in a loose form of people who meet each other on Facebook for example in a (private) group. 

As you involve more people, there is a need to organise the community as a foundation or association (e.g. to be able to receive donations). Ultimately, you also bind 'supporters' to your community, e.g. experts who are willing to support you. 

The WaihonaPedia foundation is such a supporter; we want to help your community to do as much as possible for your community members (Impact!).
