Sent 9: A recent study of the kiosks' first 18 months of operation concluded it is too soon to tell if the system will relieve pressure on court calendars.
Sent 10: But the report, by UC Irvine's School of Social Ecology, said users were overwhelmingly positive about the free legal assistance.
Sent 11: "It's made life a lot easier for me," Williams said.
Sent 12: "It's helped keep me from going to the poorhouse."Sent 13: The 29-year-old Orange resident was directed to a kiosk in the Lamoreaux Justice Center by court staff.
