if any maintainers want we can add a special maintainer role.

I applied some editorial fixes (typos etc.) in #2620.

However, regarding the change in general, I still would like to know:

• Are there other Ruby Discord servers with comparable traffic? If so, they should be listed, too.
• Is there a way to provide a proper link to the Ruby channel, instead of an invite link?

@stomar Thanks for the modifications.
At this moment, I don't know other servers which have comparable traffic. There's a lot of technical wise servers, like StimulusReflex and such.

I've generated a link with no lifetime nor click limitations, here: https://discord.gg/qbEygW9hAp

Hope it answers your interrogations.
