Its great to work on a project that has a profound impact on non profits. I am very excited about the work we do on CiviCRM which involves building on each other's ideas to create best of breed solutions for non profits. The fact that CiviCRM is an open source project with an amazing community and dedicated developers is an icing on the cake.
CiviCRM has one of the most active and friendliest communities I have come across. From initial tentative forum posts I was encouraged into engaging more actively through IRC and directly with other groups & individuals and am now happy to count many community members as friends. I recently found an article on the web that said if you post a question about CiviCRM anywhere on the web Lobo will post an answer within a few hours. It often feels like that is true.
One of the most valuable way in which the community supports me is by allowing me to bounce my ideas around and often someone is able to suggest an approach which is better than mine.
As a small and dynamic organization, the power combined with flexibility that CiviCRM offers us was crucial for our choice in choosing to use it. With my organization having used CiviCRM for more than three years and myself for around two, we try to give back to the community in whatever small ways we can - since an active community is so important to ensure the further development of this great product.
I work for the Electronic Frontier Foundation. We switched to CiviCRM so that we could be sure that our membership data stays safe, secure, and private. Now we have control over our CRM and can customize it to work for our needs.
