Get a chat program like Trillian:
http://www.trillian.cc/
It accepts all the other popular chat program details (ICQ, AIM, Yahoo, etc.) and you don't get loads of spam!
Once it's installed and setup for your particular requirements, you join the llamasoft channel like this:
Start up Trillian, then bring up the Connection Manager:

Then select:
IRC as the chat medium, Blitzed: Random server, the Nickname you want to use, an Alternate (if the one you want is already taken, you may have to re-do these if both are taken), your e-mail addy, User Info (whatever you want), then click on Save Personal Info.
You can choose whether to have these on all other chat rooms or not as you wish, click on the buttons as required.
On the next tab:

Ensure that the User ID is your primary Nickname. The others should already be there.
On the last tab:

Type in the box as shown here:
/NickServ IDENTIFY password;/join #llamasoft
Putting an actual password in where the word password is in the /Nickserv text.
Then you can click on the Connect button at top-right and you should connect,
although if you don't it may be Trillian/Blitzed has problems, or you did something wrong, so check it anyway.
If I've got anything wrong please let me know and I'll edit this post before it's made into a sticky!
