When I used to go (before I made a complete ass of myself and decided not to go back out of sheer shame), I use mIRC.
Aww, come back in hon. We'd love to have you. <3
... really? I mean... I really, really stuffed both feet square in my mouth last time I was in there... I worry I'm going to say something stupid again and that'll just be it.
Yes really. Get your butt in there before I sajoin your arse into it. ;3
Edit: Derp, you posted right as I posted.
