It seems a little confusing to have this under the L mount systems grouping. I don't even own a Leica and think it should have a forum grouping on its own, away from L mount talk, as was the case at DPR. This would be a forum for M mount, Leica medium format, and cameras like the Q. Basically any Leica.
The L mount systems forum should be a general forum for all L mount cameras (some Sigma, some Leica, some Panasonic).
