Good idea, for some reason it hasn't caught on properly yet. Strange, as there are quite a few forum members here.
I was expecting a ReShade server, though, ReShade is just a channel there.
I also found this one
discord.me/page/reshade
even smaller, but only ReShade.
A Discord server based on "graphical enhancement" in general would make sense, such as ReShade + ENB + GeDoSaTo + DSR/VSR + Graphical mods etc.
