Narrative:
While taxiing out, aircraft in line behind us radioed on company frequency that our left main gear door (forward outboard) was dangling open. After contacting maintenance and dispatcher, we returned to the gate. The door was found unlatched in the maintenance 'open' position. The first officer noticed the door was open on his preflight inspection, but assumed this was normal, as the gear doors frequently sag without hydraulic pressure applied. The maintenance latch can only be seen from inside the gear bay, and the door was not open enough to allow its viewing. The external latch handle was flush in its normal position. Maintenance found slight damage to the nacelle structure near the latch point, but determined aircraft was safe for flight and moved the damaged area to a 'non routine work control card.' we had the door latched and continued the flight.
