This document summarizes lessons learned from a participatory research and design project with seniors. Some key lessons included: (1) the research activities became community offerings that the community appropriated; (2) the community shaped the project as it proceeded, requiring an interdisciplinary team; (3) a "deep trust" approach where researchers become part of the community builds and reinforces communities. Questions are also raised about sustainability, exiting the community, generalizing findings, and supporting more participatory design projects through community informatics.
