Just noticed there's already an IRC.NET (last time i checked was years ago), so I'll just rename it to dotnetIRC (lulz).
I've been working on another quick project for CS:S, but I'll be resuming work on wpIRC and dotnetIRC now. dotnetIRC will have SSL/TLS support, numeric and other message handing, and some example code (mainly for constructors).
In other news, wpIRC will initially not support color/bold/etc. I have a way to add these, but I'm not sure if it will put a strain on resources yet.
