RE your "connection problems:"
I could honestly say that the first few times your connection "went down"
may have not been manual. They were legit "Connection reset by peers," meaning something went wrong on on your end of the connection to my network. (Either that or you used Windows Task Manager to close your client >.>)
However, when your quit message says "Quit: " in front of it, there is only one possible "cause" and that is that you typed /quit or closed the window. >_<
It's not a problem with the server, I've took more time than I should investigating it. If you're having trouble with IRC just join #Support and somebody might be able to help you. And no, I doubt a virus could cause you to quit IRC with "Quit: Png timeout"
I'm not going to permanently G:Line you or anything, just don't do it anymore, or if you think you might have connection problems, call your ISP.
