ERC
*This is an IRC client in Emacs. I'm using ZNC as an IRC bouncer, so some of this might only apply if you're using ZNC too.
1 Hiding alerts
(setq erc-hide-list '("JOIN" "PART" "QUIT"))
2 Setting default server
In spacemacs, they are set at the point of including the erc layer in your layers config.
(erc :variables erc-server-list '(("irc.example.com" :port "6770" :ssl t :nick "nick" :password "password")))
