live chat through your browser

Without having to install a chat client you can also directly chat from the browser. You can do so by following the below link:

Load Live Chat in Browser

You will be loaded to irc.vbirc.com on port 6667, and auto join the #chat channel as a vbirc_guest user. You can use : /nick YourName (no numbers and spaces or weird characters) to set your nickname. You can join other channels by typing : /join #channelname (Example: /join #help).
