Java IRC Chat

Step 1: You must enter a Nickname. Step 2: Enter your real name (optional). Step 3: Pick a server from the list.(More being added soon) 
Step 4: Click on the "Connect Now" Button. Step 5: Chat.

(Note: If you get a message like "No authorization" that means you are not allowed to connect to that server (such as if you're from a different country). Just try another server. 
If you consistently cannot connect, keep trying different servers, there are usually a few that will allow you to connect no matter what.)
