We want to pre-schedule all the sessions held in the main room Roberston 1 (200 people theatre) by the end of Monday, January 12. @RobLa-WMF and @Qgil are coordinating with the Architecture Committee, WMF Platform and Product, the owners of the Mobile, Editing, and SOA areas, and anybody else who is proposing a session for that room.
See the pre-scheduled session in the main room at https://www.mediawiki.org/wiki/MediaWiki_Developer_Summit_2015#Schedule
