I'm trying to get Pjirc to work, and I cannot figure it out.

So first of all, I am using this:
http://metairc.rpglairs.com/codegen/advanced.php

I don't know any of the general information.
I can't find securedirc.jar.

Do I need to make an irc channel first and work that way? Also, who's a good irc host?

Anything else I should know?
