- http://www.meetup.com/San-Diego-Writers/ – Meets twice a week, on Wednesdays and Saturdays
- http://www.meetup.com/Valley-Write-and-Review/ – Meets twice a month on the second and fourth Thursdays.
The first group has been around for some time. The second is just getting started (at least with Meetup; it appears some of the members have been meeting in the past).
Note that both groups have larger numbers of members than those who RSVP. Valley Write and Review limits the number of participants at each meeting to 8, so if you RSVP, you better show up or face the wrath of the organizers, those who did attend expecting there to be 7 others, or someone who didn’t sign up because the number of attendees who RSVPed already was at the limit.
