We like many churches have committees for helping to run the life of our church. We also, like many churches, have Chalice Circles for all interests to invite our members to participate in those that are interesting and relevant for them. Virtually all of our committees and chalice circles have email listservs through their respective Google Groups to keep members of each in the know about what's happening.
Each committee has not only a listserv, but also a Google drive dedicated to their unit. So committee members can share and collaborate with documents that they upload to their drive. We strive to bring our congregation closer together using the many tools of the online trade.
See the linked PDF about many of the committees and chalice circles that we have.
