The key communication tool used by 
The Institute for Open Economic Networks is their website, which they created using Sandvox.
Effective communication is important for all organizations, whether for-profit or nonprofit, and the I-Open site offers an example of how an organization can communicate timely information by establishing a blog, share more substantial information by making white papers available for downloading, and alert readers to upcoming speaking events and workshops.
