you don't upload it to mIRC....psybnc is an other client, wich serves as a server, to connect to. You simply run psybnc and in mIRC write /server yourip:psybnc_port... And then you connect to psybnc, wich redirects you to a real IRC server... it's just a bouncer.. And btw.. If you turn your computer off, you must close psybnc too, so the nick won't stay on IRC. If you want a stable psybnc wich stays up when you close your computer you'l have to have someone to host it for you (you can even trade it or buy it, as far as I know).
