We are committed to transparency
We are part of the Transparent Civil Society Initiative
The aim of the Transparent Civil Society Initiative is to create the broadest possible alliance for action within civil society that agrees on the essential parameters for effective transparency.

Those who work for the common good should tell the community:
What the organization does.
Where the funds come from.
How they are used.
Who are the decision makers.
