They just sent out a report to contributors. It is quite direct, and free of corporate-speak and weasel words. There are essentially no sales at this time ("just 19 contributors have sold at least one image") and the few that happened were due to self-promotion by the photographers themselves, ouitside of MG.
They suggest waiting another 6 months to see if something happens.
As long as they keep sending out reasonable-sounding statements I'll probably leave my (small) portfolio there, but I'm not finding the motivation to do any more.
