Hi,
https://www.mediawiki.org/wiki/Architecture_Summit_2014#Participants has been updated in order to reflect the current list of participants confirmed.
We are in touch with a few contributors from areas currently underrepresented, and it is possible that some people are still added to the list.
Volunteer contributors requiring sponsorship will be contacted via email. The Wikimedia Foundation will cover their flights and accommodation. Please email me if you don't hear from us this week.
Wikimedia Foundation employees not based in San Francisco must contact their managers for travel arrangements.
The first MediaWiki Architecture Summit 2014 is looking great at least in terms of participation. Next: content. Now it's time to focus in the discussions prior to the event, and the schedule.
