Today my #emacs package-of-the-day is https://github.com/isamert/emacs-slack
That's a fork of https://github.com/yuya373/emacs-slack maintained by @isamert
Original package couldn't start in my new corporate environment due to lots of custom emojis, rate limits, and apparently some limitations on WebSocket connections in our enterprise setup, but this fork worked perfectly!
So just wanted to express my gratitude for the maintenance.
