TL;DR: elm-conf is a single-day, one-track conference about Elm, happening September 26! The call for speakers opens today and runs through May 13.
We’ll be returning to St. Louis again this year and will be on the Strange Loop preconference day. This year we’ll be in the same space as ICFP, so you’ll get to rub elbows and chat with the wider functional programming community as well as your fellow Elm programmers.
The call for speakers is open. We want your talks! In addition to the feedback rounds you normally get, this year we’re reserving a couple of spots for first-time speakers. Full details on the speak at elm-conf page.
We’ve also got some fun stuff up our sleeves, which we’ll announce soon! 
This is also the first year that I’ve managed to make the whole conference site using Elm! (edit: this is on me, not the language 
) It does some fun things: Markdown is converted to a JSON AST and parsed on the client side. The same markdown is embedded in the HTML responses. When you load a page, Elm renders the whole screen. And, when you navigate, it only requests the JSON body to re-render.
