The Citizen Science Association (CSA), a member organization dedicated to the advancement of citizen science as a practice, maintains a discussion listserv where educators, researchers, and others engage in lively discussion and resource sharing over email. You do not have to be a member of the CSA to join. 

This listserv gives you a great window into the vast world of citizen and community science happening around the globe. If you ever have a question or a request related to citizen science, the community participating in this discussion forum is always ready to help with great ideas and resources. The Citizen Science Association also has an education working group and maintains an open-access journal called Citizen Science: Theory and Practice with plenty of content of interest to environmental educators.
