I’m not taking on additional tasks for linux.conf.au 2010 (above co-chairing the presentation selection committee with Michael Davies) and so won’t run with this, but an idea for someone with more time on their hands: a FOSSCoach miniconf or co-located event. I’m not sure whether you can call it FOSSCoach precisely (or would want to, I dislike the FOSS acronym), but the idea is an event teaching people how to work on Free Software projects. It could possibly be extended into, say, editing Wikipedia. If anyone wants to do this, go for it.
The linux.conf.au 2010 call for miniconfs is out now and is open until July 17. linux.conf.au 2010 will be held from 18–23 January 2010 in Wellington, New Zealand.
