I agree with plooker. Beyond a few sporadic contributions over the years, I only really actively started posting around this time last year, by which time I had accumulated thousands of profiles not in the system already. This is in part because Canadian variants are a bit hit and miss in terms of whether they are up there (I suspect that a few users just download the closest looking profile and don't worry if the UPCs match). I don't mind doing a movie from scratch if it's not already anywhere on DVD Profiler, but I'd never be finished if I had to always do the cast from scratch and probably wouldn't bother contributing. And copying over is often the best way of contributing uncredited cast. I'm not a large western buff so Trigger is the only uncredited actor I'm likely to spot in any westerns I do own.
