Yeah, one more with something meatier for existing F# users would have been nice.

Good news: An F# talk has been added to the agenda: "Smatterings of F#"!

It can be quite difficult to obtain that Slack access as well. It took me multiple attempts and seemingly-ignored emails before I managed to get in weeks after my first attempt. I hope I was an outlier, but I felt there was much room for improvement there.
