On 14-16 November the OpenCon 2015 conference is organised in Brussels.
This conference is about Open Access, Open Education and Open Data, which
is practically the same subject as the one of the Wikimedia movement, only
from a different perspective. Therefore I think it is good to support this
conference and visit it.
If you want to attend, sign up before 22 June: http://opencon2015.org/attend
