Hi - I'm not happy posting this, but I guess this is how things are done.
I have a niggling feeling that 'two' people I have just played doubles with are in fact the same person - or they're just good at playing at the exact same time - which I know is possible! The two in question, in my opinion, are Kennocha and Themistocles. In the game in question, 59803, they both played at the exact same time, every time - easily done with two windows open... I've had a look at other games they are both in, and the same is true of most - though not all.
Deepest apologies if there is no multi here - it was just very very suspicious!!
