Reference for thorough Mac guide to IRC (Apps & Usage)

Can someone please refer me to a simple, yet thorough, video tutorial that can help understand all I'll ever really need to know how to do when it comes to using IRC on my Mac ~ with either X-Chat Aqua or Colloquy (a written tutorial would be fine if no one knows of a video version...I do learn better by seeing though)??

I know that 90% of you have been using IRC for years and are so completely fluent in the use of IRC that my question probably seems completely idiotic to you, but for someone who has never used it before it's actually quite challenging to figure it out on my own - and simply Googling 'IRC tutorial' has typically only ever brought me to seriously outdated guides that focus on Windows IRC apps, or some other completely irrelevant IRC-related topic...

Any suggestions would be greatly appreciated... Thanks!

 

Thanks so much for your helpful response...It's nice when people actually make an effort to help by responding with some substance as you've done, rather than simply referring you to google (which often does wind up being the solution, though it also often winds up leading down a road of endless junk that doesn't ever answer the questions asked)...

Thanks again!
