Hi Moodlers,
This months font is 'Autour One' -> http://www.fontsquirrel.com/fonts/autour-one - as seen here on Shoehorn V3.0.0.3 under Moodle 3.0.1.
It is a nice rounded font that seems to be the style employed on tablets these days. Despite being a sans-serif font, it does appear to have a hint of the line flow that serif fonts exude.
Cheers,
Gareth
