Advice needed on how best to promote free NoSQL unconference a ski resort

Hi all; I've been running snowcode, a free developer unconference since 2010; The conference is non profit and is run out of our passion for snowboarding, skiing & coding, sharing and learning.

This year a few of the core regulars can't make it, and I need some help to promote the event and fill the chalet. If we can fill the new chalet we're using this year then we have a good chance that we can make this our home for many years to come; hence my call for help on hacker news.

If anyone has ideas or suggestions on where I should be posting info about the event, that would be most appreciated; Also if people could help us with some mention on social media, blogposts or tweets etc, then we'd all be incredibly grateful.

This year's snowcode NoSQL unconference is being held in La Clusaz, France (19th-26th January 2014). More info about this year's NoSQL unconference can be found on the link above, together with links to photographs and videos from the snowcode 2010, 2011 and 2012 events.

Thank you all in advance, warmest regards & keep chilling, Alan and the gang at snowcode
