Channels? Clients? Commands? Other thoughts?

Here’s what I saw on a cursory glance:

list of clients: https://www.slant.co/topics/1323/~best-irc-clients-for-linux

how to get started (dated?): https://www.linux.com/news/beginners-guide-irc/

basic commands: https://www.mirc.com/help/html/basic_irc_commands.html

channel list? https://www.irchelp.org/chanlist/

A lot of people use other chats like element / matrix these days too
