If you're wanting to get involved in SEM or the like, I highly suggest you visit the Webmaster Radio chat room. If you're a noob, I suggest you sit back and watch, don't just jump in and start asking people to fix your website.
If you've got mIRC, set the logging to save to a local text file. Then when you're away, simply change your nick (usually to something like nick_ or nick_away) and minimize your screen. That way people won't try to talk to you, and you'll log any conversations that might interest you.
