In order to foster communication between members of the San Francisco Bay Chapter, an electronic mailing list group has been created for any interested party to use.
http://www.sfbaycaving.org/sfbc-group-mailing-list/
This list is intended for SFBC members to post announcements of events, news in the caving community, meeting announcements, arrange carpools, etc.
Since this is a mailing list intended mainly for the use of cavers, the accepted culture of not disseminating the location of caves (in the United States), encouraging inappropriate caving practices, etc. should be followed.
For new cavers interested in joining on some beginner friendly trips and meeting more active participants of the grotto, we also have a new caver group.
