Same for me but the day I will really cry a little will be when mIRC dies. It was my introduction to instant effortless free worldwide communication. Of course I haven't used it for decades but it calms me that it is still very alive.
Unlike ICQ, mIRC is just an IRC client and even if it dies, the IRC networks would remain accessible using other IRC clients. That said it'd be a pity if mIRC dies.
Isn't mIRC just a client for IRC (a standard), but ICQ is centralized? Or are there some "mIRC"-branded servers out there that run popular IRC channels?
