Hey,
I created discord server for addons related discussions. The reason I did that is not everyone likes github (yes! that's true, I don't like github nor git itself nor anything related to git :P), not every player/addon author is willing to create github accout and many people already have discord account. I think discord is more players friendly than gitter and since we create our addons for players, discord seems to be good place to have some players - authors conversations. So please come in and tell your friends!
There is a role for addon authors (no special privileges, just to know who is an author) so let me know if are (link your esoui author page).
