Something I'd hoped might have been fixed in this brave new world is headcount: it seems by and large that the c.c computers are good at adding but poor at subtracting, so group member numbers are almost always overstated. Surely it should not be all that difficult to conform published numbers with actual numbers on a continuing basis ...
And while I'm on the subject of headcount, it makes rather a nonsense of things to tell us e.g. that there are more than 110,000 Australian members of chess.com if our admins are only able to identify and communicate with 100 pages worth - i.e. just 1,000 of them.... This, with respect, is rather farcical!
Under LEARN / Game Explorer: why is it that the ECO codes drop off so quickly? Here's an example from the Petroff: 1. e4 e5 2. Nf3 Nf6 3. Nxe5 Qe7, and already there's no code being displayed!!
