Y’all. I love this! Mine was the college forensics listserv IE-L (Individual Events listserv) started back in like 1993 or 1994. It worked a bit like slack actually, if all slack threads were subsequent emails. 😅
Ok, that sounds terrible today, but back before email marketing, it was kind of delightful. And I was an early adopter—and it’s how I got to know a lot of the people I only saw at weekend tournaments. Lots of passionate discussion on the intricacies of performance and proto discussions about authenticity, equity, community.
The director of my program hated it. But that was partially because it could expose some of his unprofessional behavior. It helped everyone involved feel connected and engaged, and with a voice in the larger community of individual events in forensics (public speaking and performance, not dead bodies).
There you go Charles O.

And a bonus tidbit: I’m also part of a Slack community that has well over a hundred channels!
…now me personally, I absolutely love it, because it starts so many new conversations around topics, and periodically it gets pruned just a tad. But I know this would be scary for some folks. Not for the community, and that’s the whole point 😆
