IRC from your browser! It's going to ask you if you want to run something.. you do. No, it won't fuck up your computer, it's PJIRC. Look it up. A nickname will be magically chosen for you, from the username you use to login to this website. Isn't that grand? Be patient, it may take a while for someone to return your greeting, but rest assured someone will, even if it's just old tiko. ;)
If you don't have Java installed, it won't work. I suppose that means you should install Java.. from here.
