'''Un-Conference:''' helps people to make connections, share knowledge, collaborate and inspire each other. To take part, participants are encouraged to give a presentation, create a discussion, or even chair a debate (http://lanyrd.com/blog/2012/unconference-howto/ ; http://openspaceworld.org/wp2/what-is/). This format can be relatively egalitarian and relatively easy to organise but you should watch out for the tyranny of structurelessness. If not well organised in advance they can become very ineffective. They can also be extremely intimidating and therefore exclusionary towards less experienced or skilled participants; and can be stressful if you need to organise tech or other resources for specific activities in advance. Events such as the Ada Camps (https://adacamp.org/) or the TransHackFeminist convergence (http://transhackfeminist.noblogs.org/) have been using the model of un-conferences for instance.
