The 2017 MariaDB Developers Conference is taking place in New York City from 9-10 April.
M|17, the MariaDB User's Conference, is taking place directly afterwards, so if you're in the area, why not attend both :)
It's free to attend for everyone interested and you are welcome to sign up on the Meetup Group, as well to propose a topic, or vote for an existing topic.
