Out of curiosity why Buzz and not Discord if you're looking for a Slack alternative?
My experience trying to get Discord and/or Slack to work was painful for 1 agent, let alone the potential for hundreds.
Here's the perfect example of the power of Buzz: there was some hype today about Grok Bot so i wanted to spin it up. I did, and within like 3 minutes, I had a Grok Bot talking to my other agents in Buzz, and Buzz is definitely not a supported plugin.
