Hi I'm the owner of a mid size poker discord that's been around for almost 2 1/2 years. I currently play 500-2knl on app sites, many of the people who joined 1-2 years ago are now playing midstakes as well. I personally started at 10nl and was able to move up with help from the discord. We also have some free content to share, mainly there is hand history analysis and talk about BBV/Mindset/poker life in general but we've done voice calls and sweat sessions in the past.
I would say 50nl+ is preferred as most guys are at that level but anyone who is willing to contribute is welcome
Add me - microbro#7503 and I can invite you.
