Once again, the LWF (Department for Mission and Development) is planning a 'virtual conference'. It was brilliant in 2013, and I would encourage you to check it out. It will be held on 18th September, 2014 and will again feature highly diverse speakers, be accessible in five languages (English, Spanish, German, French and Indonesian) and have engaging conversations.
More detailed information will be available towards the end of June 2014. The bonus is the opportunity to connect with diaconal colleagues (even if you're not Lutheran!), and there is no travel involved so dramatically reduces carbon dioxide emissions.
Knowing that access to internet is not as easy to access nor low cost for everyone, the organizers are setting up a solidarity fund for the conference to assist others with the cost to access the internet in cafes etc.
