I also wish open-source communities would move off of Discord for another reason: Users are limited to joining a maximum of 100 servers.
I've hit the cap and it's driving me crazy. It's really easy to hit it since each friend group, hobby group, gaming community, and open-source community often all have their own servers.
That limit is per account, right?
I can barely keep up with 6 semi active discord servers, each with tens of semi active channels... Much less think about doing it with hundreds. More power to you, must have figured out a good notification scheme
