Coincidentally, that same month, a Yahoo! Group was formed that was also devoted to L.A./Southern California (digital) photography:
LA dSLR Group is for anyone in the Los Angeles/Southern California area with a passion for photography. Emphasis is on digital SLR cameras, but all enthusiasts are welcome regardless of equipment or skill level. Members learn, expand, and share their knowledge of photography (including postprocessing) through reguarly scheduled photo trips, educational seminars, constructive feedback of member photos, and technical discussions.
As of this writing, there are 78 members of that group and 351 messages for this month alone.
