You have probably read the announcement of the Wikimedia Developer Summit
2016 registration and call for participation.
https://www.mediawiki.org/wiki/Wikimedia_Developer_Summit_2016
I just want to stress that this year we are putting a special emphasis on
inviting not only the developers of MediaWiki core, extensions, and APIs,
but also the "other" developers using this platform to create gadgets,
bots, templates, tools, apps, and third party products relying on Wikimedia
APIs.
We want to increase their participation bringing their own proposals and
joining others' as stakeholders, and we want to meet with them during the
event in San Francisco. We have a modest sponsorship travel budget for
those registering before OCTOBER 2nd (deadline for presentation of new
proposals).
Reaching out to all these developers is not simple, as they are quite
spread. Your help forwarding our invitation to the appropriate communities,
mailing lists, Talk pages, etc, is very welcome.
