Eth0:2012 Summer Villages
The idea of villages is self-organization. Most groups coming to events like this are self-sufficient enough to take up part of the more low-level organization, like renting a common tent and doing some networking. Or in some cases organize events/lectures of their own. Since every group has their own interests and ideas this creates a more distributed feel to the event.
Drinks & Food
While food and beverages for your own needs are of course perfectly fine, you cannot run your own bar or otherwise sell food or drinks. Don't worry, there will be a well-equiped bar.
Fire and Safety
If you are planning on having larger tents, drop the team a line at irc so they can check if anything special needs to be arranged.
