Are you clicking the link, or going to the [B]IRC Chat[/b] button on the homepage? If you're clicking the link, it's not going to work.

Go the home page, dude. [b]Chat[/b] is at the very top, but to the right and down slightly is a button that says IRC. Hit that button and it'll prompt you for a name, and you should be on "mibbit chat". When you're in, type in:

/join #pokemon

and you should be good to go.

Follow those steps and tell me what y'all get. I was able to jump off and on 3 times on a stable connection using Chrome, we can troubleshoot from there if that doesn't work.
