Series mod allowed me to post this thread so I posted here. Here is the server for the people who are interested in speedrunning Tetris games: https://discord.gg/wwNDmzhNgQ

Just replying to push this a little higher after my replies in other threads.
I want to note that this is not officially endorsed as a Tetris series Discord server, but I figure that to the people interested in speedrunning Tetris, it's a nice place to stop by anyway.
