IRC is a form of instant communication over the Internet. It is intended for group (many-to-many) communication in discussion forums called channels, but also allows one-to-one communication. The easiest way to join our chatroom when you are using Puppy is to click on the Chat icon on the desktop or find it in the menu.
irc://irc.freenode.net/puppylinux in your browser and then pick your nickname. If that doesn't work then enter irc.freenode.net as the chat server and #puppylinux as the channel in the appropriate places.
Freenode Web Access site and any browser. You may either enter a fictions nickname or if you have a Freenode registered nickname then click the check box for Auth to services and then enter your nickname and password.
