You can find this blog at @TaTM_blog (since someone beat me to any of the more obvious ones).
You can find me, personally, at @fleetfootmike, where I've always been, but do be warned that my range of hobbies and interests ranges far and wide beyond wargaming to everything from domestic solar power, cricket, guitar, politics, Christianity and tea to science fiction, Fleetwood Mac, Formula 1, computer programming and railways, and most points in between.
Twitter thinks I should follow Chris Moyles, Katy Perry and Nicole Scherzinger. I'm not convinced.
