mIRC the client, IRC the service/protocol. Espernet was my old home.
I utterly loved that client too, and it was my first foray into scripting. So much customisation, slap scripts, trivia bots etc etc. The da-da-da-da-ding of new connections and private messages....
Then of course there was XDCC for obtaining a whole plethora of media & games...
Support. Logged into this alt just to say so.
Feeds are nicer without it. For new users, all it does is drive them back to Reddit - a place they very likely just left.
