MozFest 2019: 21-27 October, London
@RoseLanigan, @ayduns, @michaelmcandrew & myself attended MozFest in 2018, with a session: - "Chose your Own SMS Adventure with CiviCRM" — managed here: community/presence-at-events#1 (closed).
We were scheduled first thing on the opening morning at the far end of the venue from the opening speeches, which overran by 15 mins, so didn't reach capacity. But we did pitch for $5000 from their Open Source fund, and got it (managed here https://lab.civicrm.org/community/fundraising/milestones/1). Worth considering another session for their ten year anniversary festival?
