In case you didn't know, Fandom is planning to merge with fellow website Gamepedia, which will result in the website's software being upgraded and thus, certain features like message walls and article comments are being retired to be replaced with other, similar features later down the line. Expect this to happen around January 2020.
In the meantime, we already have a discord server (https://discord.gg/3Rw6c74) where much of us discuss wiki related matters. Discussions themselves will also be kept.
